pdních

pdních is a term that has appeared in a limited set of linguistic discussions to label a family of morphophonological phenomena. In this usage, pdních describes patterns in which the phonological shape of a morpheme changes when it combines with other morphemes, in a way that depends on the syntactic or semantic environment.

Etymology and status: The coinage appears to be a neologism with unclear origin. It is not part of established grammars or core reference works and is largely encountered in informal writings, working notes, and some online forums. Because of its limited attestation, there is no widely accepted formal definition of pdních.

Characteristics: The discussions typically emphasize three aspects: (1) environment-sensitive allomorphy at morpheme boundaries, (2) cross-linguistic examples suggesting a typological pattern, and (3) its relation to broader questions about how phonology interacts with morphology and syntax. Some authors treat pdních as a provisional label for phenomena that will later be integrated into existing frameworks rather than a separate theory.

Examples: In a hypothetical language, the stem pan- followed by suffix -dar yields pandár, while the same stem pan- followed by suffix -níh yields pandníh. In another case, a verbal stem ku- plus suffix -a can surface as -kua, whereas with suffix -i as -ki, illustrating how the final sound of a stem interacts with the following morpheme.
