Translativestem

Translativestem is a theoretical construct in morphology describing the invariant part of a word that is used when forming translative forms, i.e., those that express change of state or becoming into another category or state. In languages with a translative case or mood, affixes attach to the translativestem to signal becoming or moving into a state or class. The translativestem may be identical to the lexical stem of the word, or it may undergo phonological or formal alternations such as consonant gradation or vowel modulation that are specific to translative morphology.

Identification and analysis: To identify the translativestem, linguists compare multiple data points of a word’s translatively formed forms and related cases; the part that remains constant across translative derivations is the translativestem. It is distinct from the derivational stem, which yields new words, and from the inflectional stem, which is used for non-derivative grammatical forms.

Cross-linguistic use: Not all languages have a translative category or a translative suffix; among those that do, the translativestem behaves differently. In agglutinative systems, it is often a fixed morphophonemic base; in fusional systems, it may involve alternating allomorphs.

Applications: The concept is used in typological syntax and historical reconstruction to understand how change-of-state meaning is distributed across stems and affixes. It may also be relevant in conlang development where translative morphology is designed.
