Usage notes
Tio-avô has two plural forms, tios-avôs and tios-avós. The former means exclusively a group of two or more men (cf. English great-uncles), the latter is used for a group of both men and women. Both are masculine nouns. The plural of tia-avó (great-ant) is a regular feminine noun (tias-avós) and means great-aunts. This is one of the few Portuguese nouns that have a tripartite plural inflection, the others being, , , and other derived terms.
