Adherir is a Spanish verb which translates into English as “to adhere, stick on”.
Below are all of the conjugations for adherir 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 adhere, stick on |
|---|---|
| Spanish Infinitive | adherir |
The gerund (gerundio) is used with the continuous tenses, e.g. present continuous (está adhiriendo) and past continuous (estaba adhiriendo). The easiest way to think of it is the equivalent of english’s -ing form (e.g. adhering).
The past participle (participio) is used with perfect tense ‘haber’ verbs, e.g. he adherido and hubiera adherido. These are the equivalent of English’s ‘have’ (e.g. have adhered).
| Gerundio / Gerund | adhiriendo |
|---|---|
| Participio / Past Participle | adherido |
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 adhere” or “they adhere”.
| Pronoun | Spanish |
|---|---|
| Yo | adhiero |
| Tú | adhieres |
| Él / Ella / Usted | adhiere |
| Nosotros / as | adherimos |
| Vosotros / as | adherís |
| Ellos / Ellas / Ustedes | adhieren |
| Vos | adherís |
Your simple past tense, e.g. “I adhered” or “she adhered” 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 | adherí | I adhered |
| Tú | adheriste | You adhered |
| Él / Ella / Usted | adhirió | He / she / you adhered |
| Nosotros / as | adherimos | We adhered |
| Vosotros / as | adheristeis | You adhered |
| Ellos / Ellas / Ustedes | adhirieron | They / you adhered |
| Vos | adheriste | You adhered |
The pretérito imperfecto roughly translates as “I was adhering” or “she was adhering” 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 | adhería | I was adhering |
| Tú | adherías | You were adhering |
| Él / Ella / Usted | adhería | He was / she was / you were adhering |
| Nosotros / as | adheríamos | We were adhering |
| Vosotros / as | adheríais | You were adhering |
| Ellos / Ellas / Ustedes | adherían | They / you were adhering |
| Vos | adherías | You were adhering |
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 adhered” and “she has adhered”.
| Pronoun | Spanish | English |
|---|---|---|
| Yo | he adherido | I have adhered |
| Tú | has adherido | You have adhered |
| Él / Ella / Usted | ha adherido | He has / she has / you have adhered |
| Nosotros / as | hemos adherido | We have adhered |
| Vosotros / as | habéis adherido | You have adhered |
| Ellos / Ellas / Ustedes | han adherido | They / you have adhered |
| Vos | has adherido | You have adhered |
The conditional is used in place of the English modal verb “would”, i.e. “I would adhere” or “she would adhere”. It can be used to talk about hypothetical situations.
| Pronoun | Spanish | Englush |
|---|---|---|
| Yo | adheriría | I would adhere |
| Tú | adherirías | You would adhere |
| Él / Ella / Usted | adheriría | He / she / you would adhere |
| Nosotros / as | adheriríamos | We would adhere |
| Vosotros / as | adheriríais | You would adhere |
| Ellos / Ellas / Ustedes | adherirían | They / you would adhere |
| Vos | adherirías | You would adhere |
The future tense, simply put, replaces the English modal verb “will” – i.e. “I will adhere” or “they will adhere”.
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 adherir” means “They are going to adhere”.
| Pronoun | Spanish | English |
|---|---|---|
| Yo | adheriré | I will adhere |
| Tú | adherirás | You will adhere |
| Él / Ella / Usted | adherirá | He / she / you will adhere |
| Nosotros / as | adheriremos | We will adhere |
| Vosotros / as | adheriréis | You will adhere |
| Ellos / Ellas / Ustedes | adherirán | They / you will adhere |
| Vos | adherirás | You will adhere |
| Pronoun | Spanish |

| Vos | adhieras |
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 | adhiriera | adhiriese |
| Tú | adhirieras | adhiriese |
| Él / Ella / Usted | adhiriera | adhiriese |
| Nosotros / as | adhiriéramos | adhiriésemos |
| Vosotros / as | adhirierais | adhirieseis |
| Ellos / Ellas / Ustedes | adhirieran | adhiriesen |
| Vos | adhirieras | adhiriese |
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.

| Tú | adhirieres |
| Él / Ella / Usted | adhiriera |
