repelidas

Repelidas is the feminine plural past participle of the Spanish verb repeler. In usage, repelidas functions as an adjective or as part of a passive construction to describe feminine plural nouns that have been repelled or rejected. It agrees in gender and number with the noun it modifies, as in las partículas repelidas por el campo eléctrico or las fuerzas repelidas por la barrera. The corresponding forms are repelidos (masculine plural), repelida (feminine singular), and repelido (masculine singular).

Etymology lightly notes that repelidas derives from repeler, itself from Latin repellere, with the typical -ido past participle suffix in Spanish. In scientific and technical writing, repelidas is commonly used to indicate objects or entities that have been driven away or opposed by a force or barrier, such as particles or waves. In broader or figurative contexts, speakers may prefer synonyms like rechazadas or expulsadas, depending on nuance, since repelidas emphasizes a direct act of repulsion rather than mere rejection.
