Convertí

Convertí is the first-person singular form of the Spanish verb convertir in the pretérito indefinido, also known as the simple past. It expresses a completed action in the past and corresponds to “I converted” or “I turned” in English, depending on the context. While it can refer to changing physical form, it is also used for broader transformations, including changes in status, opinion, or data.

Conjugation in the pretérito indefinido is irregular in the third person forms. The full set for convertir is: yo convertí, tú convertiste, él convirtió, nosotros convertimos, vosotros convertisteis, ellos convirtieron. The first two forms use the regular endings with the stem convert-, but the third person forms involve a stem change to convirt-: convirtió, convirtieron. The acute accent on í in convertí marks the past tense and helps distinguish it from present-tense forms such as convierto or conviertes.

Usage notes: convertí is used to describe actions completed in the past. It frequently appears in narrative or when reporting specific past events. In contrast, to talk about habitual past actions or ongoing states, other tenses such as the imperfect (convertía) or the present perfect would be more appropriate. The verb can cover a wide range of meanings—from physical transformation (convertir formatos, unidades) to figurative changes (convertirse en algo).
