'aumery' originates from Old French, specifically the word 'almerie', where the element 'alme/alm-' referred to 'alms' or charitable gifts (related to Late Latin 'almonaria').

'aumery' changed from medieval Latin/Old French forms such as medieval Latin 'almonaria' and Old French 'almerie' and eventually became the English form 'aumery' (also seen historically as 'aumerie' or 'almery').

Initially it meant 'a place for alms' (a room or chest for charitable gifts), but over time its usage broadened to include 'a pantry or storeroom' in some contexts; the word is now archaic.
