### machüühati *“he does not fling (various times).”* The form **machüühati** is built upon the root *achüüha*, “to fling (various times)” (NISAMINA master dictionary). 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 fling (various times)” — its gloss states the fully-inflected sense, never the bare meaning of the root. Among the forms built on the same root, **nachüüha** (“I fling (various times)”); **bachüüha** (“you fling (various times)”): 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. While a citation of this exact form still awaits collection, its root is heard in living speech, as in *“yurüdü / achuuhati / fuluri”* — ‘hummingbird ('colibrí')’ (es: ‘colibrí’). [FEED:Mar_a_Trinidad_S_nchez_Pineda] *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 rath
