- Fortis and lenis
Fortis (
Latin "strong") and lenis ("weak") are linguistic terms. In a broad sense, they refer to the opposition ofconsonant s such as "p", "t" vs. "b", "d". In a narrow sense, fortis refer to consonants such as "p", "t" pronounced withtenseness (more muscular tension) and lenis to consonants such as "b", "d" pronounced without.History and use of the terms
These terms were already used in 19th century German linguistics to describe languages such as southern German where consonants such as "b", "d" are voiceless but nonetheless different from "p", "t". The terms fortis and lenis are used in current descriptions for the contrast in consonants in many Zapotec languages.
Opposition of "p", "t" versus "b", "d"
Normally, the opposition of consonants such as "p", "t" vs. "b", "d" is described in terms of
voiceless consonant s vs.voiced consonant s. There are languages where this is indeed the only feature that distinguishes them ("e.g." French IPA| [p, t] vs. IPA| [b, d] ). In many languages, however, the phonetic voice is only one of several features that constitutes this opposition (e.g. English: IPA IPA| [pʰ, tʰ] vs. IPA| [b, d] ). There are even languages where the phonetic voice is not a distinctive feature of these pairs at all (e.g. southern German, Danish or Mandarin: IPA IPA| [pʰ, tʰ] vs. IPA| [p, t] ).The terms "fortis" and "lenis" (in the wide sense) apply to this opposition regardless of whether it's only an opposition of voice or not. Using English as an example, this means that when we devoice a voiced consonant, (such as 'd' at the end of a word,) for ease of articulation, it still retains the fortis / lenis distinction. This is not true of Polish, where the voiced consonant retains only the place of articulation and becomes fortis. Thus the terms fortis and lenis allow one to describe in more precise terms than 'voiced and unvoiced' the articulation of French, English, Polish and southern German consonants. They refer to a bundle of articulatory features which have different distributions in different languages. Not all of them need to be present in a particular language:
*voice
*length
*aspiration
*tenseness Tenseness
It is commonly said that tenseness is what distinguishes "fortis" and "lenis" in the narrow sense: In the articulation of the "fortis", more muscular energy is supposedly used. However, this has never been demonstrated.
In Korean, a higher fundamental frequency of vowels following certain 'tense' consonants is thought to be a result of increased muscular tension in the vocal cords, a phonation called
stiff voice . However, inSwiss German , no possible acoustical correspondent of the assumed tenseness has been found. Consequently, it is debated whether theSwiss German opposition is really based on different muscular tension, and not ongemination .The
North Caucasian languages (Circassian and Dagestanian) have a consonantal distinction described as strong or preruptive that has concomitant length. Akhvakh and other Dagestanian languages even possess a distinction between strong/long and weak/shortejective consonants: [IPA|qʼaː "soup", "broth" vs. [IPA|qːʼama "cock's comb." (Tense phonemes in these languages are traditionally transcribed with the length diacritic, following the Cyrillic orthography of these languages.) Kodzasov (1977:228, translated in L&M 1996:97–98) describes them for Archi: "Strong phonemes are characterized by the intensiveness (tension) of the articulation. The intensity of the pronunciaiton leads to a natural lengthening of the duration of the sound, and that is why strong [consonants] differ from weak ones by greater length. [However,] the adjoining of two single weak sounds does not produce a strong one […] Thus, the gemination of a sound does not by itself create its tension." Nonetheless, Ladefoged and Maddieson examined Kodzasov's Archi recordings, and their impression was that "length should be given the primary role; strong consonants have approximately twice the duration of weak ones, and they often do result from adjoining two single consonants, at least morphologically speaking. The patterns in other Dagestanian languages are similar, but some Agul dialects have an especially large number of permitted initial long consonants." Fortis stops inAustralian languages such as Rembarrnga also involve length, with short consonants having weak contact and intermittent voicing, and long consonants full closer, a more powerful release burst, and no voicing. It is not clear if strength makes the consonants long, or if during long consonants there is greater opportunity for full articulation.Articulatory strength can reinforce other distinctions. The
Ewe language , for example, which contrasts avoiceless bilabial fricative IPA|/ɸ/ and avoiceless labiodental fricative /f/, pronounces the /f/ markedly more strongly than /f/ in most languages, in contrast with the weaker IPA|/ɸ/. This helps differentiate what would otherwise be an exceedingly subtle distinction. Phonetically, a diacritic from theExtensions to the IPA can be used to indicate this strong articulation: IPA| [ɸ] vs. IPA| [f͈] .In the Mixe-Zoquean language Mixe the distinction between consonants described as fortis and lenis has been demonstrated to be one of quantity: fortis consonants are pronounced longer than their lenis counterparts, and they are also not prone to voicing in voiced environments such as the lenis consonants are.
Notation
The IPA provides no means for a representation of a fortis-lenis contrast since the signs IPA| [p t k f s x …] vs. IPA| [b d ɡ v z ɣ …] explicitly represent a voice contrast. The
Extensions to the IPA provide a diacritic for strong and weak articulation. As that diacritic is seldom used, there is a number of other notations:*The fortis-lenis contrast may be transcribed with plain IPA| [p t k f s x …] vs. IPA| [b d ɡ v z ɣ …] even though this is in contradiction to their IPA definition that relies solely on voice. This notation emphasizes that the voice contrast and the fortis-lenis contrast are thought of as manifestations of a common sound feature.
*The fortis-lenis contrast may be transcribed as a gemination contrast. This emphasizes that it is unrelated to the voice contrast.
*The fortis-lenis contrast may be transcribed as IPA| [p t k f s x …] vs. IPA| [b̥ d̥ ɡ̊ v̥ z̥ ɣ̊ …] , that is, the lenes are marked with the IPA diacritic for voicelessness. By strict IPA definition, this appears contradictory because if [p] and [b] differ but in their voicedness, then a IPA| [b̥] that is voiceless should be identical to a [p] . This notation emphasizes that there is more than just voice to the contrast between IPA| [p t k f s x …] vs. IPA| [b̥ d̥ ɡ̊ v̥ z̥ ɣ̊ …] . It is sometimes used in the transcription of Southern German dialects such as Alsatian orSwiss German .ee also
