### áwagachagubeiyein *“he has always been opening one's mouth (continuously / habitually, up to now).”* The form **áwagachagubeiyein** is built upon the root *áwagacha*, “to open one's mouth” (The People's Garifuna Dictionary (Cayetano)). To it is joined the perfect-continuous suffix *-gubeiyein*, which stretches the action across all past time up to the present, 'has always been …-ing' (the *-yein* marking a masculine subject). Taken whole, the word means precisely “he has always been opening one's mouth (continuously / habitually, up to now)” — its gloss states the fully-inflected sense, never the bare meaning of the root. Placed beside its siblings, **náwagacha** (“I open one's mouth”); **báwagacha** (“you open one's mouth”): 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.*
