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,
