Lactar conjugation

Table of Contents

Lactar is a Spanish verb which translates into English as “to nurse, breast-feed”.

Below are all of the conjugations for lactar in Spanish, in all three moods (indicative/indicativo, subjunctive/subjunctivo and imperative/imperativo) and all of the tenses, for each pronoun.

The vosotros pronoun is mainly used in mainland Spain, and is the informal second-person plural – it could be considered the Spanish version of “y’all”. It is rarely found in Latin America, where ustedes is used instead.

The vos form is used instead of tú in some Spanish speaking countries of South America, especially the Southern Cone (e.g. Argentina and Uruguay) and has a different conjugation.

Spanish Infinitive lactar

Lactar Gerund and Past Participle

The gerund (gerundio) is used with the continuous tenses, e.g. present continuous (está lactando) and past continuous (estaba lactando). The easiest way to think of it is the equivalent of english’s -ing form (e.g. breastfeeding).

The past participle (participio) is used with perfect tense ‘haber’ verbs, e.g. he lactado and hubiera lactado. These are the equivalent of English’s ‘have’ (e.g. have breastfed).

Nosotros / as lactamos We breastfed

Lactar Perfect / Perfecto

The perfect tense is for talking about things which happened in the past but are still related to the present or continue into the present.

In English, these use the auxiliary verbs ‘have’ and ‘has’ – i.e. “I have breastfed” and “she has breastfed”.
