compusisteis

Compusisteis is the second person plural form of the Spanish verb componer in the pretérito indefinido (simple past). It corresponds to the English “you all composed” or “you all put together.” The verb componer means to compose, create, or assemble something, such as a musical piece, a text, or a mixture or arrangement. In the preterite, componer uses an irregular stem: compus-, giving the full set compuse, compusiste, compuso, compusimos, compusisteis, compusieron. The form compusisteis thus combines the irregular stem with the standard -isteis ending of the vosotr as past tense.

Formation and usage notes: compusisteis is derived from the combination of the prefix com- and the stem pus- from poner, adapted in the preterite as compus-. This irregular stem is shared with the other preterite forms of componer (e.g., compusisteis, compusieron). The tense is used to describe actions completed in the past, often referring to creating a work, fixing, or assembling something.

Regional considerations: the vosotos form compusisteis is standard in Spain and in some contexts in other Iberian-speaking communities. In many Latin American varieties, speakers may prefer the corresponding vosotros forms in informal speech, while using ustedes + preterite forms for past actions (e.g., ustedes compusieron) in regular narrative contexts. Nonetheless, compusisteis remains correct in contexts that use the vosotros form.

Examples:

- Compusisteis una canción muy buena para la película.

- Ayer compusisteis la lista de invitados para la boda.
