The Bemba Verb Equation

An elegant and complete morphological framework. Bantu verbs operate as complex mathematical pipelines where prefix and suffix slots are bound to lexical stems to construct full sentences inside a single word.

The Structural Formula
Verb = S1 + S2 + S3 + S4 + S5 + S6 + S7 + S8 + S9

Pre-Initial (S1) + Subject (S2) + TAM (S3) + Object (S4) + Root (S5) + Extension 1 (S6) + Extension 2 (S7) + Final Vowel (S8) + Post-Final (S9)
