Realizaron

realizaron is the third‑person plural form of the Spanish verb realizar in the simple past (pretérito) tense, used to indicate that a group of subjects performed, carried out, or completed an action in the past. The verb realizar derives from the Latin realisare, meaning “to make real” or “to bring into being,” and in modern Spanish it functions both transitively and intransitively. In its transitive use, realizar means “to execute,” “to accomplish,” or “to carry out,” as in “Los ingenieros realizaron la prueba” (The engineers carried out the test). In an intransitive or reflexive construction, it can convey “to become aware” or “to realize” mentally, for example “Se dieron cuenta y realizaron que el proyecto era inviable” (They realized that the project was unfeasible).

Conjugated in the pretérito perfecto simple, realizaron belongs to the regular –ar verb pattern: yo realicé, tú realizaste, él/ella realizó, nosotros/nosotras realizamos, vosotros/vosotras realizasteis, ellos/ellas realizaron. The form appears frequently in narrative texts, news reports, and academic writing when describing completed collective actions. Its usage aligns with standard Spanish grammar rules and is recognized across Spanish‑speaking regions, though variations in lexical preference may arise, with synonyms such as efectuar, ejecutar, cumplir, or llevar a cabo sometimes substituting in specific contexts.
