sustituyó

Sustituyó is the third-person singular preterite form of the Spanish verb sustituir, meaning to replace someone or something with another. It indicates that in the past, a person or thing took the place of another. Sustituir is transitive and can describe replacing people, objects, roles, or functions, as in employment, sports, technology, or education.

Etymology and forms: Sustituir comes from Latin substītuere, from sub- (in place of) and statuere (to place). In the preterite, the 3rd person singular form is sustituyó (with the accent on the ò) and the 3rd person plural is sustituyeron, reflecting the -uir verb pattern in Spanish. Related words include sustitución (substitution), sustituto/sustituta (substitute), and similares.

Usage and examples:

- El entrenador sustituyó al delantero lesionado. (The coach substituted the injured forward.)

- La empresa sustituyó el equipo antiguo por uno más moderno. (The company replaced the old equipment with a newer one.)

- En la clase, la maestra sustituyó al profesor ausente. (In class, the teacher substituted for the absent professor.)

Sustituyó thus functions across formal and informal registers to convey past acts of replacement, with nuances ranging from temporary replacements to permanent substitutions depending on context.
