### áhürüchaguarugu *“in the habit of grating (cassava, coconut) / doing nothing but grating (cassava, coconut).”* The form **áhürüchaguarugu** is built upon the root *áhürücha*, “to grate (cassava, coconut)” (NISAMINA master dictionary). To it is joined the habitual-restrictive suffix *-guarugu*, which fixes the action as a habit or sole occupation — 'in the habit of …-ing, doing nothing but'. Taken whole, the word means precisely “in the habit of grating (cassava, coconut) / doing nothing but grating (cassava, coconut)” — its gloss states the fully-inflected sense, never the bare meaning of the root. To see its precise force, compare **náhürücha** (“I grate (cassava, coconut)”); **báhürücha** (“you grate (cassava, coconut)”): 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 MARAGAÑ (Shaka) MAGARADA 2026-06-24 (eibuga aspect family: -dugu frequentative / -gubeiyein perfect-continuous). 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.*
