aplaudaste

Aplaudaste is the second-person singular form of the Spanish verb aplaudar in the pretérito perfecto simple (preterite). It denotes a completed action in the past and is used when addressing someone informally as “tú.” The regular form reflects the standard -ar verb conjugation: aplaudé, aplaudaste, aplaudó, aplaudamos, aplaudasteis, aplaudaron.

In many dialects that use voseo, such as Argentina and parts of Uruguay, the same form aplaudaste is also used with the pronoun vos in the preterite, yielding vos aplaudaste. In formal contexts, the verb is conjugated as usted aplaudó or ustedes aplaudaron, corresponding to the third-person singular or plural.

Etymology and origin: aplaudar comes from the verb’s Romance heritage, with roots linked to the Latin plaudere (to clap). The modern Spanish form is related to cognates in other Romance languages, such as the French applaudir, and developed through the standard evolution of -ar verbs in Spanish.

Usage notes: Aplaudaste is common in narrative or descriptive passages that recount a past event involving clapping, such as performances, speeches, or ceremonies. Because it is a regular form, it occurs in both spoken language and written texts, with ambiguity between tú and vos generally resolved by the available pronoun or regional context. Examples: “Tú aplaudaste al final.” “Vos aplaudaste cuando terminó la función.”
