Affricates

Is there a specific reason articulation of combinations like [pɹ] as an affricate is judged to be impossible while /d͡ɹ̝/ is considered an affricate?
In an affricate, both components are homorganic, i.e. produced by the same articulator. [pɹ] combines a labial with an alveolar sound, thus no affricate. (Also, [ɹ] is not a fricative.)yangfiretiger121 wrote:Is there a specific reason articulation of combinations like [pɹ] as an affricate is judged to be impossible while /d͡ɹ̝/ is considered an affricate?
That is not homorganic.vergil wrote:How does something like [tʙ] feature into this homorganicism?
right, but it's still sometimes called an affricate.Travis B. wrote:That is not homorganic.vergil wrote:How does something like [tʙ] feature into this homorganicism?
Probably the best measure is whether something can slot into the syllable structure as a unitary entity, or whether something has to be treated as a cluster with regard to syllable structure and syllabification, metricality, and so on. Unfortunately, making this determination is not always possible (e.g. languages with complex onsets and codas in the first place where syllable weight has little consequence so thus cannot be used as a distinguishing measure).Nortaneous wrote:right, but it's still sometimes called an affricate.Travis B. wrote:That is not homorganic.vergil wrote:How does something like [tʙ] feature into this homorganicism?
[tʙ] seems to be very rare. I don't know much about the languages where it occurs, but "Linguistics: An Introduction (William B. McGregor, 2015) describes it as an "unusual coarticulated phone".vergil wrote:How does something like [tʙ] feature into this homorganicism?
I also found an article called "Prestopped bilabial trills in Sangtam", by Alexander Coupe, that refers to /t͡ʙ/ and /t͡ʙ̥ʰ/ using the phrasing in the title, and puts them in a separate row from the affricates in the table of Northern Sangtam phonemes.There is [...] a very rare voiceless alveolar bilabially trilled affricate, [t̪͡ʙ̥] (written ⟨tᵖ̃⟩ in Everett & Kern) reported from Pirahã and from a few words in the Chapacuran languages Wari’ and Oro Win. The sound also appears as an allophone of the labialized voiceless alveolar stop /tʷ/ of Abkhaz and Ubykh, but in those languages it is more often realised by a doubly articulated stop [t͡p]. In the Chapacuran languages, [tʙ̥] is reported almost exclusively before rounded vowels such as [o] and [y].
One should distinguish phones where multiple POA are articulated simultaneously with affricates, where there is a plosive at one POA immediately followed by a fricative release at the same POA or a very close POA (e.g. German /pf/) which behaves as single unit for the purposes of phonotactics.vec wrote:Coarticulate = heterorganic cluster that behave as single phoneme
Affricate = coarticulate of homorganic plosive and fricative
So, an affricate is a subset of coarticulates. Coarticulates must be 1) homorganic, 2) stop+fricative, in order to be defined as affricates.
