obstruiste

Obstruiste is a Spanish verb form that functions as a past tense conjugation rather than a standalone word with a defined concept. Specifically, obstruiste is the second-person singular preterite (past) indicative form of the verb obstruir, which means to obstruct, impede, or block.

Etymology and meanings: The verb obstruir comes from Latin obstruere, formed by ob- (against, toward) and struere (to pile, build). In modern Spanish, obstruir is used to describe obstructing physical passage, delaying processes, or hindering progress, among other senses. The preterite form obstruiste is used when the subject is you (informal, singular) and the action was completed in the past, e.g., Tú obstruiste el paso al cerrar la puerta.

Conjugation context: Obstruir is a regular -ir verb in its imperfect and present forms, but it is part of the -uir group in the preterite, which affects certain forms. The full preterite paradigm around obstruiste is: yo obstruí, tú obstruiste, él obstruyó, nosotros obstruimos, vosotros obstruisteis, ellos obstruyeron. The second-person form obstruiste is common in narrative and everyday speech.

Usage notes: Obstruiste appears primarily in Spanish-language texts when recounting past actions by a specific person. It is not a technical term in linguistics. In phonetics, related but separate terms describe obstruents—consonants formed with significant airflow obstruction—rather than verb forms like obstruiste.
