Adelgazar is a Spanish verb which translates into English as “to make thin, get slim slender, lose weight”.
Below are all of the conjugations for adelgazar 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.
| English Infinitive | to make thin, get slim slender, lose weight |

| Spanish Infinitive | adelgazar |
The gerund (gerundio) is used with the continuous tenses, e.g. present continuous (está adelgazando) and past continuous (estaba adelgazando). The easiest way to think of it is the equivalent of english’s -ing form (e.g. making thin).
The past participle (participio) is used with perfect tense ‘haber’ verbs, e.g. he adelgazado and hubiera adelgazado. These are the equivalent of English’s ‘have’ (e.g. have made thin).
| Gerundio / Gerund | adelgazando |

| Participio / Past Participle | adelgazado |
The basic form of speech, el indicativo is used for making statements, talking about facts, events and things that are certain and objective.
The present tense is as it sounds – it’s for talking about things that are currently going on, which are habitual, or which generally exist. In English, this would be “I make thin” or “they make thin”.
| Pronoun | Spanish |
|---|---|
| Yo | adelgazo |
| Tú | adelgazas |
| Él / Ella / Usted | adelgaza |
| Nosotros / as | adelgazamos |
| Vosotros / as | adelgazáis |
| Ellos / Ellas / Ustedes | adelgazan |
| Vos | adelgazás |
Your simple past tense, e.g. “I made thin” or “she made thin” in English.
In Spanish, there are two past tenses where just one is used in English; the pretérite infefinido is typically used to refer to a concrete, specific moment in time.
| Pronoun | Spanish | English |
|---|---|---|
| Yo | adelgacé | I made thin |
| Tú | adelgazaste | You made thin |
| Él / Ella / Usted | adelgazó | He / she / you made thin |
| Nosotros / as | adelgazamos | We made thin |
| Vosotros / as | adelgazasteis | You made thin |
| Ellos / Ellas / Ustedes | adelgazaron | They / you made thin |
| Vos | adelgazaste | You made thin |
The pretérito imperfecto roughly translates as “I was making thin” or “she was making thin” in English, and is typically used to describe things and set a scene, talk about events without a specific timeframe, or talk about habitual events or states in the past.
| Pronoun | Spanish | English |
|---|---|---|
| Yo | adelgazaba | I was making thin |
| Tú | adelgazabas | You were making thin |
| Él / Ella / Usted | adelgazaba | He was / she was / you were making thin |
| Nosotros / as | adelgazábamos | We were making thin |
| Vosotros / as | adelgazabais | You were making thin |
| Ellos / Ellas / Ustedes | adelgazaban | They / you were making thin |
| Vos | adelgazabas | You were making thin |
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 made thin” and “she has made thin”.
| Pronoun | Spanish | English |
|---|---|---|
| Yo | he adelgazado | I have made thin |
| Tú | has adelgazado | You have made thin |
| Él / Ella / Usted | ha adelgazado | He has / she has / you have made thin |
| Nosotros / as | hemos adelgazado | We have made thin |
| Vosotros / as | habéis adelgazado | You have made thin |
| Ellos / Ellas / Ustedes | han adelgazado | They / you have made thin |
| Vos | has adelgazado | You have made thin |
The conditional is used in place of the English modal verb “would”, i.e. “I would make thin” or “she would make thin”. It can be used to talk about hypothetical situations.
| Pronoun | Spanish | Englush |
|---|---|---|
| Yo | adelgazaría | I would make thin |
| Tú | adelgazarías | You would make thin |
| Él / Ella / Usted | adelgazaría | He / she / you would make thin |
| Nosotros / as | adelgazaríamos | We would make thin |
| Vosotros / as | adelgazaríais | You would make thin |
| Ellos / Ellas / Ustedes | adelgazarían | They / you would make thin |
| Vos | adelgazarías | You would make thin |
The future tense, simply put, replaces the English modal verb “will” – i.e. “I will make thin” or “they will make thin”.
It is more commonly used for making a hypothesis about the present. To talk about the future, Spanish speakers frequently use “ir + a + infinivo”, e.g. “van a adelgazar” means “They are going to make thin”.
| Pronoun | Spanish | English |
|---|---|---|
| Yo | adelgazaré | I will make thin |
| Tú | adelgazarás | You will make thin |
| Él / Ella / Usted | adelgazará | He / she / you will make thin |
| Nosotros / as | adelgazaremos | We will make thin |
| Vosotros / as | adelgazaréis | You will make thin |
| Ellos / Ellas / Ustedes | adelgazarán | They / you will make thin |
| Vos | adelgazarás | You will make thin |
| Pronoun | Spanish |

There are two ways to form the imperfect subjunctive.
The first option sees verbs ending in -era (for -er and -ir verbs) and -ara (for -ar verbs), while the second sees verbs ending in -ese (for -er and -ir verbs) and -ase (for -ar verbs).
There is no difference between these two forms, and Spanish speakers use them interchangeably.
| Pronoun | Spanish era/ara | Spanish ese/ase |
|---|---|---|
| Yo | adelgazara | adelgazase |
| Tú | adelgazaras | adelgazase |
| Él / Ella / Usted | adelgazara | adelgazase |
| Nosotros / as | adelgazáramos | adelgazásemos |
| Vosotros / as | adelgazarais | adelgazaseis |
| Ellos / Ellas / Ustedes | adelgazaran | adelgazasen |
| Vos | adelgazaras | adelgazase |
The future subjunctive is no longer used in modern-day Spanish, apart from in literary and legal contexts, and there is no need to learn it.
It is formed the same as the past/imperfect subjunctive, but with -e endings instead of -a endings.
| Pronoun | Spanish |
|---|---|
| Yo | adelgazare |
| Tú | adelgazares |
| Él / Ella / Usted | adelgazare |
| Nosotros / as | adelgazáremos |
| Vosotros / as | adelgazareis |
