### agumuleduwagueina *“while being added.”* The form **agumuleduwagueina** is built upon the root *agumuleduwa*, “to be added” (Lila Garífuna Diccionario (Suazo)). To it is joined the simultaneous suffix *-gueina* ('while'), which sets the action as the backdrop to another — 'while …-ing' (allomorphs -heina/-guena). Taken whole, the word means precisely “while being added” — its gloss states the fully-inflected sense, never the bare meaning of the root. Placed beside its siblings, **nagumuleduwa** (“I be added”); **bagumuleduwa** (“you be added”): 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.*
