prolongaron

Prolongaron is the third-person plural form of the pretérito indefinido (simple past) of the Spanish verb prolongar. It corresponds to "they prolonged" and can also be used with ustedes in regions where ustedes is used as the second-person plural. This form marks a completed action in the past in which something was extended in time, scope, or duration.

Etymology and morphology: prolongaron comes from prolongar, whose etymology traces to Latin prolongare, formed from pro- (forward, forth) and longus (long). In Spanish, -aron is the standard ending for the third-person plural in the pretérito indefinido for verbs of the -ar conjugation, with the root prolong- intact.

Usage: The form is common in narrative and descriptive past contexts. It is used when describing events in which the duration or extent of something was extended, such as deadlines, periods, or procedures, and it typically appears with a subject that is ellos, ellas, or ustedes (formal you plural). The verb is regular in this tense, without irregular stem changes.

Examples:

- Los investigadores prolongaron el estudio durante dos años.

- Las autoridades prolongaron el plazo para presentar alegaciones.

- Ustedes prolongaron la vigencia del acuerdo hasta nuevo aviso.
