Abstract

Asthma, wheeze and cough are words with profoundly differing histories, etymologies and meanings. Yet their medical usage today is clustered around the diagnosis and management of a single disease. Hitherto, asthma has been a clinical diagnosis but wheeze, cough and asthma now are key terms in cross-cultural questionnaire surveys which seek information on asthma prevalence. In this essay, we examine differences in the linguistic properties of terms likely to be relevant to interpreting large-scale variations in asthma prevalence uncovered by questionnaires. We show how etymologically distinct each term is: while asthma and cough each share semantic congruencies across six European languages, albeit for different reasons, there is less congruence across these languages for the term wheeze. The medical meanings of all three terms contrast with meanings revealed by the non-medical usage of all three terms, which are highly figurative. Linguistic considerations indicate that interpretation of international questionnaires that phrase questions in terms of cough, asthma and their derivatives are likely to be more reliable for the purposes of comparing prevalence than those which deploy questions phrased in terms of wheeze.


‘We ought only to bring in a new name if it indicates a real species with distinct specific qualities; otherwise the practice is pointless.’1

INTRODUCTION

Asthma is a common label, but the trickiness of its definition and the variability in its usage have been compared with the definition and usage of a notion as complex as love.2 For most of its discernible history, asthma was used in medicine (adverbially) to qualify certain sorts of breathing difficulty. It was only in the 17th century that ‘an asthma’ was viewed as a condition in its own right, when asthma (the noun) came to be qualified with one of many possible adjectives at the time: hysterical, flatulent, convulsive, uterine, peptic, spasmodic, nervous, bronchial or cardiac asthma—aetiologies which would have been suggested by the clinical history.

Coughing, wheezing, whistling and hissing sounds associated with disordered breathing were features physicians found notable when diagnosing asthma. However, the invention of percussion in the 18th century3 and the development of mediate auscultation with invention of the stethoscope in the 19th century4 drew physicians' attention away from the oral testimony of patients when diagnosing asthma, turning it towards the search for clinical signs.5 Until the end of the 20th century, the diagnosis of asthma was inherently clinical, dependent on close contact and exchange of information between patients and doctors. However, end of century multi-centre epidemiological studies, such as the International Study of Asthma and Allergies in Childhood (ISSAC) and the European Community Respiratory Health Survey (ECRHS), bypassed clinical exchange of information and used, instead, self-completed questionnaires reliant on key word descriptors to elicit information diagnostic of asthma from populations speaking different languages.6,7

Such questionnaires are predicated on the modern trend towards greater parsimony of symptom description in the medical definition of asthma and on assumed closer correspondence between certain word descriptors and underlying patho-physiological processes believed to be important in disease mechanisms in asthma (e.g. bronchoconstriction). Yet lay discussions of breathing disorders continue to evoke much more elaborate descriptions of symptoms associated with shortness of breath and laboured breathing, which are not easily or fully reducible to ‘wheeze’ or ‘exercise induced broncho-spasm’ or ‘cough’.8 So today, asthma is a diagnosis strongly suggested by the utterance of, or by ticking a box containing, certain key words: wheeze; whistling; difficulty breathing; cough; cough on exertion; or cough at night in bed. But do such words uttered in different languages by different discourse communities reliably label similar facts and support clinical diagnoses?

On the one hand, the meaning of terms derives, in part, from what they denote—i.e. from what they discernibly and reliably refer to; on the other hand, their meaning tends to change because language usage evolves, altering meanings, including the meanings of terminologies. Different words (or combinations of words) can denote the same thing, may have the same literal referent such as ‘wheeze’ and ‘musical sounds in my chest’ (of a certain frequency), which medically trained ears translate as bronchoconstriction. However, the same term used by members of different speech communities, may have quite different referents: ‘shortness of breath’ can refer to difficulty in breathing, to rapid breathing and/or to breathlessness, all of which describe different states of affairs (and sensations). In addition, outside of the medical context these terms tend to carry quite different metaphorical meanings.

The literal referents of some words can be more discrete than those of others. For example, ‘wheeze’ refers to a sound (and possibly a sensation) behaviourally and aurally much less distinct than that denoted by its rhyming sister ‘sneeze’. The word ‘cough’, on the other hand, has a distinct though complex behavioural referent.

Critical terms for the diagnosis of asthma can be studied by tracing them back to their roots etymologically and by examining their modern use. Etymology, ‘the study of the historical relation between a word and the earlier form or forms from which it has developed’9 is important to medicine because it can help explain how these terms and concepts have evolved.10 In this essay, we trace how three particular terms became medically associated, by looking at the etymology of the words in English and comparable terms in other European languages and by looking at their usage in modern English.

We used dictionaries of etymology and word origin to trace the origin of asthma, wheeze and cough, and electronic dictionaries to translate and back translate these words into other European languages (see Appendix 1). Collections of electronic editions of literary works in English were searched, and we also traced early use of the word ‘asthma’ in Greek using the Perseus Collection, an on-line library of classical Greek and Latin texts.11 We searched Medline for articles with these terms in their title in English and in other European languages.

Because the meanings of words are constantly in flux as a result of usage, we went beyond etymology and examined social usage of these terms using linguistic resources. We searched the British National Corpus (BNC), a corpus of approximately 100 million words in English.12 We searched for ‘cough’, ‘coughed’, ‘coughing’, ‘coughs’, ‘asthma’, ‘asthmatic’, ‘asthmatics’, ‘wheeze’, ‘wheezed’, ‘wheezing’, ‘wheezes’, and studied in detail a random sample of 50 from each of the total number of hits for each term. Usage of each of these terms was classified as ‘medical’ if the word was used to denote some kind of difficulty breathing or if clearly used as a medical term, ‘metaphorical’ if used metaphorically and ‘alternative’ if used in some other way (e.g. wheeze as a clever scheme). The quotes from the BNC identify the source of each usage with an alpha-numerical identifier.

The earliest recorded use in English is that of cough (c. 1325), followed by asthma (c. 1398) and wheeze (verb c. 1460, noun c. 1834).13

COUGH

From the Middle English coughen, the word is onomatopoetic, echoing the sound which it denotes. Johnson derived its origin from Dutch kuch, and defined it as ‘a convulsion of the lungs, vellicated by some sharp serosity.’14 In German and Italic languages, words with roots in Latin tuss are employed and have entered English as tussive.

ASTHMA

The word ‘asthma’ has a long history. Derived from the Sanskrit vayu meaning ‘wind’, it found its way into Greek as α' ίω (to blow), and through Latin entered Middle English as asma. The term was not originally associated with disease. Homer's use of the term ‘pant’ (άσθμα) to describe extreme breathlessness of battle weary heroes—Hector after his near defeat by Ajax (Iliad, Book 15, line 241) and Ajax, himself, during his last battle with the Trojans (Iliad, Book 16, line 109)15—seem to have ensured that the experiential content of laboured breathing which is denoted by panting became a semantic component of the term asthma as it evolved in European culture. In subsequent centuries the word was popularized in Greek drama as άσθματOζ (Aeschylus 525-456 BCE, Persians)16 and in poetry (Pindar 518-438 BCE, Nemean Odes).17 Hippocrates (460-370 BCE) used the term asthma (άσθμα) to refer to a condition of laboured breathing and noted its seasonal relation to autumn (Aphorisms, Section 3, 22) and to middle age (Aphorisms, Section 3, 30).18 By the first century CE, asthma was used to describe a state of sickness, the word then referring to laboured, rapid, and putrid breathing of the afflicted Herod (Flavius Joseph, 37-100 CE, Antiquitates Judaicae).19

A more detailed treatment of asthma in ancient Greek medical literature can be found in Marketos and Ballas.20 Onians, in an extensive review of ideas about breath in European thought, points out that Greek άίω and άίσθω refer to breathing in as a ‘taking ’ of some thing, as in άίσθoμαl (or άίσθάνoμαl), ‘I perceive’.21 Asthma, or a closely related word such as asthme in French, or acma in Slavic, is in use today in each of the six modern European languages we examined, the term being used to describe a medical condition (Table 1).

WHEEZE

Wheeze is derived from the Indo-European root kwes also meaning ‘to pant’; it moved into Germanic as hwsjan and Old Norse as hvæsa (‘to hiss’) before entering Middle English as whesen. In their origins, wheeze and asthma have a similar meaning, each carrying reference to experiences of laboured breathing associated with fighting. Kwes is also the root of the Sanskrit word kAsa meaning cough and thus links wheeze etymologically with cough. Recent usage has paired wheeze with whistle (wheezing or whistling) in medical questionnaires (see Box 1), especially because whistle calls attention to the musical nature of wheeze in those languages in which wheeze has no meaning. However, the origin of whistle is quite different (Old English hwistlian and Middle English whistlen) from wheeze.

Although the term wheeze has semantic relations with the word pant, it became commonly employed to refer to a sound characterized by a frequency of some 210-280 Hz,22 a sound held to have a ‘musical’ quality. Forgacs compared the mechanism of wheeze to the production of sound by a toy trumpet.23 To translate the term wheeze into languages where there is no equivalent term, etymologically quite different terms such as squeaking (meaning the sound made by small animals especially rodents, from Middle English squeken, perhaps of Scandinavian origin) have been used.24

Box 1 Key questions from two trans-national self-completed asthma prevalence questionnaires

ISAAC

Have you ever had wheezing or whistling in the chest at any time in the past?

Have you ever had asthma?

In the past 12 months, have you had a dry cough at night, apart from a cough associated with a cold or chest infection?

ECRHS

Have you had wheezing or whistling in your chest at anytime in the last 12 months?

Have you been woken by an attack of coughing at any time in the last 12 months?

Have you had an attack of asthma in the last 12 months?

There is no term for wheeze in Dutch. Piepen, used by Dutch people to denote rhonchi (from Greek ρoγχoζ (rhoncus), snore or rattling sound), is a term used to describe squeaky sounds. German pfeifen describes sounds which in English may be translated as howl, whistle, swish, or whine. A whistling sound in French is sifflante and was used to denote what in English we call wheeze. In addition to sifflante, the verbs siler and siffler are verbs used to denote wheezing.25 Other Italic languages use various forms of Latin sibilans, sibilant-, the present participle of sibilare, meaning to hiss. Interestingly, patterns of more recent usage as found on the titles of medical papers suggest ‘wheeze’ and ‘wheezing’ are becoming nosological terms like asthma; it is now not uncommon to hear clinicians refer to ‘wheezing disorders’.26

USES OF COUGH, ASTHMA AND WHEEZE IN CURRENT ENGLISH

In the BNC, cough and related words were the most frequently used of these terms, followed by asthma and wheeze (Table 2). But whereas cough, asthma and their derivatives almost always carry a medical meaning as used in the BNC, wheeze and its derivatives do so on only just over half the occasions they are used (95/161=59%). All three groups of terms were used mainly in their medical sense, and asthma and its forms were almost always so used. Rarely, asthma can be used as a simile (‘The vastness was closing in, choking me like asthma27) or metaphorically (The windscreen wipers sounded asthmatic...28). We also found asthma used comically (... floundering like an asthmatic salmon...29).

Like asthma, cough related terms were also predominantly used in their usual medical sense. However, the productive nature of cough has given rise to the metaphor for producing anything, especially money (Sickly Britons coughed up £438 million on health remedies last year...30). The noise produced by expelling air forcefully by machinery, for example, is referred to by cough (The bus threw itself into gear, coughed, and started off noisily31). In an alternative sense, cough is also used to describe the sound produced to call attention, to cover up or fill in an awkward moment (Mrs Clamp... coughed politely32).

Wheeze, referring to a whistling sound, was used in 59% of samples and in its informal meaning of a clever trick or plan was found in 31%. Like cough, wheezing, the sound, was also attributed to non-human sources (The wipers began to wheeze as the snowflakes built up...33). With the use of wheeze came the metaphor of lungs as bellows, especially that of a musical instrument (Between every phrase, his lungs wheezed like broken bellows;34 Haverford... wheezed like a rusty concertina35). Reverse instances were also found, in which the metaphor of laboured breathing was applied to music (they heard a cracked wheezing, the unskilled sequence of chords of a sea-shanty played at half speed36).

CONCLUSIONS

Words are of central importance to medicine as most of what occurs in clinical encounters is talk.37 Words denote disease and convey experiences of it; they also influence critically the design and response to medical questionnaires. But words change their meaning in response to many pressures. Medicalization of common words (as we show, asthma was a word originally used to describe laboured breathing not a disease) may have its counterpart in the colloquialization of medical terms (wheeze being used as a surrogate for asthma in epidemiological prevalence surveys). Medical reporting often shifts from ‘medical’ language to ‘personal’ language38 in its attempt to appropriate facets of reality that match different users' perspectives.39

It is when perspectives may significantly differ—as they do between clinician and patient, and epidemiologist and survey participant—that language can be critical in highlighting conceptual similarities and differences. We find considerable historical and cross-cultural differences in the meanings and usages of present-day terms adopted to diagnose and to refer to asthma. Our efforts to establish lexical equivalence between different European languages for key words used in the diagnosis of asthma are akin to the technique of back translation used for cross-cultural adaptation of survey questionnaires. In attempts to achieve this, certain terms are reduced to a set of alternative linguistic codes which are believed to carry the same literal referents justifying equivalence in usage.40,41

Our analysis reveals that the terms asthma and cough are almost always used with a medical meaning in the BNC and share semantic congruencies across six European languages (asthma because of Greek/Hippocratic influence and cough perhaps because of the imitative nature of its origin). Across these languages there appears to be much less congruence in the case of the term wheeze, which has had its medical meaning transformed on at least two occasions—from symptomatic of great effort (i.e. panting) to descriptive of musical sounds and, most recently, from descriptive of musical sounds to something nosological (i.e. denoting a disease entity) and in the BNC wheeze and its derivatives are used with medical meaning on only 59% of occasions sampled. Because the medical semantic framework of wheeze is in transition questionnaire based reliance on its use for international prevalence comparisons needs to be interpreted with care.

Use of language is constantly changing as a result of creative acts expressing new thoughts and experiences. Consequentially, the meanings of words cannot be captured (or simply derived) from dictionary definitions alone, nor can their meanings be reduced (as Aristotle may have believed)1 simply to the object(s) or performances to which they may refer—in this case to behaviours labelled panting, wheezing or coughing—because new developments in the way such words are deployed, reused and abandoned within human discourses and utterances inevitably create new meanings. As Wittgenstein indicated, naming something is not always a form of specific labelling, for when a thing is named, it does not preclude the name carrying metaphorical and other meanings within the overall ‘language-game’42 which this study clearly shows.

Asthma, when used medically to denote a disease, carries a narrower range of meanings than when used nonmedically. The same is also true of wheeze and, to a lesser extent, of cough. Wheeze is clearly a term that takes on quite different meanings in differing communities of discourse, understanding of which differs between individuals and groups.43-45 While professional usage tends to harmonize overall usage, technical medical terms may well retain differing semantic associations:

The doctors ask: does he wheeze or rattle? But you know, all these words. I think it can be difficult to distinguish. Because he never wheezes... he breathes like a bull... he snorts.’46

The extent to which non-medical usages influence patient responses to questionnaires across different cultures and languages remains unknown. Lay usage of asthma terms is subject to change not least from the influences of professional discourse; increasing lay awareness of wheeze as a key medical term may alter thresholds at which people apply terms like wheeze and wheezing to all sorts of respiratory symptoms and may account in part for secular trends in asthma prevalence.47

The interpretation of questions based on use of the descriptors cough and asthma in international prevalence questionnaires may be more linguistically reliable than questions based on the term wheeze: a finding which has implications for studies such as ISAAC and ECRHS, which assume that semantic variability in their use across languages and cultures is minimal. This hypothesis is supported by the responses to the video questionnaire in ISAAC, which highlighted variability in the understanding of wheeze among the participants and the parents.48,49 Our conclusion could be tested empirically, by calling up subgroup samples of different language respondents of such trans-national studies and undertaking a linguistic study of the variance in usage of terms such as asthma, wheeze and cough, linking usages of these terms to objective measures of asthma/nonasthma status.
