### áüdübühagubeiyanu *“they have always been menstruating (continuously / habitually, up to now).”* The form **áüdübühagubeiyanu** is built upon the root *áüdübüha*, “to menstruate” (The People's Garifuna Dictionary (Cayetano)). To it is joined the perfect-continuous suffix *-gubeiyanu* (3PL), which carries 'they have always been …-ing'; on a negative stem it reads 'they have never been' (cf. meigigubeiyanu 'they have never eaten'). Taken whole, the word means precisely “they have always been menstruating (continuously / habitually, up to now)” — its gloss states the fully-inflected sense, never the bare meaning of the root. Placed beside its siblings, **náüdübüha** (“I menstruate”); **báüdübüha** (“you menstruate”): 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.*
