Fiarse de is a Spanish verb which translates into English as “to trust, rely on”.
Below are all of the conjugations for fiarse de 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 trust, rely on |

| Spanish Infinitive | fiarse de |
The gerund (gerundio) is used with the continuous tenses, e.g. present continuous (está ) and past continuous (estaba ). The easiest way to think of it is the equivalent of english’s -ing form (e.g. trusted).
The past participle (participio) is used with perfect tense ‘haber’ verbs, e.g. he trusted and hubiera trusted. These are the equivalent of English’s ‘have’ (e.g. have trusting).

| Participio / Past Participle | trusted |
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 trust” or “they trust”.
| Pronoun | Spanish |
|---|---|
| Yo | |
| Tú | |
| Él / Ella / Usted | |
| Nosotros / as | |
| Vosotros / as | |
| Ellos / Ellas / Ustedes | |
| Vos | te fiás de |
Your simple past tense, e.g. “I trust” or “she trust” 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 | I trust | |
| Tú | You trust | |
| Él / Ella / Usted | He / she / you trust | |
| Nosotros / as | We trust | |
| Vosotros / as | You trust | |
| Ellos / Ellas / Ustedes | They / you trust | |
| Vos | You trust |
The pretérito imperfecto roughly translates as “I was trusted” or “she was trusted” 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 | I was trusted | |
| Tú | You were trusted | |
| Él / Ella / Usted | He was / she was / you were trusted | |
| Nosotros / as | We were trusted | |
| Vosotros / as | You were trusted | |
| Ellos / Ellas / Ustedes | They / you were trusted | |
| Vos | You were trusted |
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 trusting” and “she has trusting”.
| Pronoun | Spanish | English |
|---|---|---|
| Yo | he trusted | I have trusting |
| Tú | has trusted | You have trusting |
| Él / Ella / Usted | ha trusted | He has / she has / you have trusting |
| Nosotros / as | hemos trusted | We have trusting |
| Vosotros / as | habéis trusted | You have trusting |
| Ellos / Ellas / Ustedes | han trusted | They / you have trusting |
| Vos | has trusted | You have trusting |
The conditional is used in place of the English modal verb “would”, i.e. “I would trust” or “she would trust”. It can be used to talk about hypothetical situations.

| Tú | You would trust | |

The future tense, simply put, replaces the English modal verb “will” – i.e. “I will trust” or “they will trust”.
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 fiarse de” means “They are going to trust”.

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.

|---|---|---|
| Yo | ||
| Tú | ||
| Él / Ella / Usted | ||
| Nosotros / as | ||
