This is very common in natlangs, but I have never seen a work using a particular term for it. Authors usually just say that a phoneme has allophones in free variation except in some particular contexts.quinterbeck wrote: ↑Wed Oct 02, 2019 2:39 am Is there a term for when an underspecified phoneme becomes specified in a certain environment? For example I have underspecified /c/ appearing as [tʲ] and [kʲ] in free variation, but always [tʲ] after /n/. Anyone suggest a better term than 'POA specification'?
An example would be much of Colombian Spanish, where lenited /ʝ/ can be [ɟʝ] or [ʝ], but non-lenited /ʝ/ (in utterance-initial position and after a nasal, and for many speakers also after /l ɾ/) can only be [ɟʝ]. E.g. mayo [ˈmaɟʝo] ~ [ˈmaʝo], un yanqui [uɲ ˈɟʝanki]. In Spanish as a whole, /p t/ can be either [β ɣ] or [p k] before word-internal /t/, but elsewhere they must be [p k]. E.g. actuar [aɣˈtwaɾ] ~ [akˈtwaɾ], opción [opˈsjon].
Neither "morphophoneme" or "archiphoneme" seem that appropriate because they represent either the complementary distribution or the contextual merger of two otherwise distinct phonemes, respectively, whereas you're asking about the presence or absence of free variation.
