Voiced alveolar plosive to Voiceless bilabial plosive

The direct, unconditioned historical phonetic shift from a voiced alveolar plosive (/d/) to a voiceless bilabial plosive (/p/) is not widely attested as a regular, unconditioned sound change. However, this transformation can occur as a result of regressive assimilation, where the alveolar stop takes on the place of articulation and voicing characteristics of a following bilabial voiceless stop.

Regressive Assimilation, Devoicing

Language Examples

ad-pellō→appellō— The alveolar /d/ of the prefix 'ad-' assimilates in place and voicing to the following bilabial voiceless /p/ of 'pellō'.
