### ínwiahaguanarugutibu *“you only whistle / you simply whistle (does nothing but whistle).”* The form **ínwiahaguanarugutibu** is built upon the root *ínwiaha*, “to whistle” (The People's Garifuna Dictionary (Cayetano)). To it are joined the element *-guanarugu* (RST 'only / simply / merely'), whose force is given by the elder paradigm; then the element *-tibu* (2SG agentive (no prefix)), whose force is given by the elder paradigm. Taken whole, the word means precisely “you only whistle / you simply whistle (does nothing but whistle)” — its gloss states the fully-inflected sense, never the bare meaning of the root. Set against its kin, **nínwiaha** (“I whistle”); **bínwiaha** (“you whistle”): 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); MARAGAÑ (Shaka) MAGARADA 2026-06-24 (constant-habitual -guadügü/-guarügü/-guadugu 'constantly / for no apparent reason'). 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.*
