inúmeras

Inúmeras is a Portuguese adjective used to indicate a very large number of things, describing feminine plural nouns. It expresses an indefinite, considerable quantity and can be translated as "countless," "innumerable," or "numerous" in English. The masculine counterpart is inúmeros, while the feminine singular form is inúmeras and the masculine singular form is seldom used in modern language. The word derives from in- (a prefix of negation or emphasis) and número (number), from Latin numerus, meaning "number." The combination conveys the sense of “not countable,” or at least too many to count.

In usage, inúmeras appears in formal and informal contexts alike, especially in journalism, literature, and everyday speech. It commonly modifies feminine plural nouns, for example: inúmeras possibilidades, inúmeras pessoas, inúmeras evidências. The expression emphasizes breadth of quantity rather than a precise count, serving as an intensifier rather than a numeral.

Notes of nuance include that inúmeras highlights abundance without quantification, suitable when the exact number is unknown or unnecessary. For precise tallies, numerals or other quantifying phrases would be used instead. Related forms include inúmeros (masculine plural) and inumerável (a closely related adjective meaning "innumerable" or "boundless" in a more formal register).
