Convertirse Conjugation | How to Conjugate Convertirse in Spanish

Convertirse means “to become” or “to turn into.” You will learn its required pronominal clitics, its e-to-ie and e-to-i changes, and how convertirse en expresses transformation into a new state.

Convertirse conjugation at a glance

Verb type: Irregular. Linguistically, convertirse is a pronominal -IR verb. Its present has me convierto — “I become” — but nos convertimos — “we become.” Its preterite changes e → i only in third-person forms such as se convirtió — “he / she became” — and se convirtieron — “they became.” The gerund is convirtiéndose — “becoming.”

Convertirse gerund, past participle, and infinitive

The infinitive names the verb, the gerund supports progressive constructions, and the past participle combines with haber — “to have” as an auxiliary — in compound forms. With haber, the participle does not agree with the subject.

Form	Spanish	Natural English guide
Infinitive	convertirse	to become, to turn into
Gerund	convirtiéndose	becoming
Past participle	convertido	converted
Compound infinitive	haberse convertido	to have become
Compound gerund	habiéndose convertido	having become

Because this target is pronominal, the clitic remains part of its non-finite behavior: convirtiéndose — “becoming” — attaches se to the gerund, while haberse convertido — “to have become” — and habiéndose convertido — “having become” — attach the clitic to haber, not to the participle.

Convertirse meaning and essential uses

Convertirse — “to become” or “to turn into” — is pronominal in the target use, so the clitic changes with the subject: Me convierto — “I become,” te conviertes — “you become,” and se convierte — “he / she becomes.”

The common transformation pattern is convertirse en — “to become / turn into.” For example, El agua se convierte en hielo. — “The water turns into ice.” The preposition en introduces the resulting state or identity.

Convertirse irregular conjugation patterns

Convertirse combines pronominal clitics with two stem-change families. In stressed present forms, e → ie: me convierto — “I become,” te conviertes — “you become,” and se convierten — “they become,” while nos convertimos — “we become” — and os convertís — “you all become” — keep e. In the preterite, only third-person forms shift e → i: se convirtió — “he / she became” — and se convirtieron — “they became.” The present subjunctive mixes conviert- in stressed rows with convirt- in nosotros/nosotras and vosotros/vosotras, while the imperfect and future subjunctive inherit convirt- from the preterite. The gerund is convirtiéndose — “becoming.”

Because the target is pronominal, attach the clitic and recompute spelling and stress: conviértete — “become,” conviértase — “become” for formal singular address, convirtámonos — “let’s become,” convertíos — “become” for plural informal address in Spain, and conviértanse — “become” for plural address.
