### mtiaraguati *“he does not agree.”* The form **mtiaraguati** is built upon the root *tiaragua*, “to agree” (The People's Garifuna Dictionary (Cayetano)). To it are joined the privative-negative prefix *m-*, which negates the action or denies the quality outright; then the third-person masculine ('he') agreement suffix *-ti*, which fixes the subject as third-person masculine ('he'). Taken whole, the word means precisely “he does not agree” — its gloss states the fully-inflected sense, never the bare meaning of the root. To see its precise force, compare **ntiaragua** (“I agree”); **btiaragua** (“you agree”): each shares the same stem yet bends it to a different shade of meaning, which is exactly how Garífuna wins great precision from a single root. *The construction rests on Haurholm-Larsen 2016 §3.3.4 (-ti/-tu); Munro & Gallagher, 'Garifuna Negatives' (m- verbal negation). This is a principled composition — a cited root joined to a cited paradigm — and so it is offered for fluent-elder validation rather than asserted as attested.*
