Infiltrar is a Spanish verb which translates into English as “to infiltrate”.
Below are all of the conjugations for infiltrar 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 | infiltrar |
The gerund (gerundio) is used with the continuous tenses, e.g. present continuous (está infiltrando) and past continuous (estaba infiltrando). The easiest way to think of it is the equivalent of english’s -ing form (e.g. infiltrating).
The past participle (participio) is used with perfect tense ‘haber’ verbs, e.g. he infiltrado and hubiera infiltrado. These are the equivalent of English’s ‘have’ (e.g. have infiltrated).
| Gerundio / Gerund | infiltrando |
|---|---|
| Participio / Past Participle | infiltrado |
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 infiltrate” or “they infiltrate”.
| Pronoun | Spanish |
|---|---|
| Yo | infiltro |
| Tú | infiltras |
| Él / Ella / Usted | infiltra |
| Nosotros / as | infiltramos |
| Vosotros / as | infiltráis |
| Ellos / Ellas / Ustedes | infiltran |
| Vos | infiltrás |
Your simple past tense, e.g. “I infiltrated” or “she infiltrated” 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 | infiltré | I infiltrated |
| Tú | infiltraste | You infiltrated |
| Él / Ella / Usted | infiltró | He / she / you infiltrated |
| Nosotros / as | infiltramos | We infiltrated |
| Vosotros / as | infiltrasteis | You infiltrated |
| Ellos / Ellas / Ustedes | infiltraron | They / you infiltrated |
| Vos | infiltraste | You infiltrated |
The pretérito imperfecto roughly translates as “I was infiltrating” or “she was infiltrating” 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 | infiltraba | I was infiltrating |
| Tú | infiltrabas | You were infiltrating |
| Él / Ella / Usted | infiltraba | He was / she was / you were infiltrating |
| Nosotros / as | infiltrábamos | We were infiltrating |
| Vosotros / as | infiltrabais | You were infiltrating |
| Ellos / Ellas / Ustedes | infiltraban | They / you were infiltrating |
| Vos | infiltrabas | You were infiltrating |
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 infiltrated” and “she has infiltrated”.
| Pronoun | Spanish | English |
|---|---|---|
| Yo | he infiltrado | I have infiltrated |
| Tú | has infiltrado | You have infiltrated |
| Él / Ella / Usted | ha infiltrado | He has / she has / you have infiltrated |
| Nosotros / as | hemos infiltrado | We have infiltrated |
| Vosotros / as | habéis infiltrado | You have infiltrated |
| Ellos / Ellas / Ustedes | han infiltrado | They / you have infiltrated |
| Vos | has infiltrado | You have infiltrated |
The conditional is used in place of the English modal verb “would”, i.e. “I would infiltrate” or “she would infiltrate”. It can be used to talk about hypothetical situations.
| Pronoun | Spanish | Englush |
|---|---|---|
| Yo | infiltraría | I would infiltrate |
| Tú | infiltrarías | You would infiltrate |
| Él / Ella / Usted | infiltraría | He / she / you would infiltrate |
| Nosotros / as | infiltraríamos | We would infiltrate |
| Vosotros / as | infiltraríais | You would infiltrate |
| Ellos / Ellas / Ustedes | infiltrarían | They / you would infiltrate |
| Vos | infiltrarías | You would infiltrate |
The future tense, simply put, replaces the English modal verb “will” – i.e. “I will infiltrate” or “they will infiltrate”.
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 infiltrar” means “They are going to infiltrate”.
| Pronoun | Spanish | English |
|---|---|---|
| Yo | infiltraré | I will infiltrate |
| Tú | infiltrarás | You will infiltrate |
| Él / Ella / Usted | infiltrará | He / she / you will infiltrate |
| Nosotros / as | infiltraremos | We will infiltrate |
| Vosotros / as | infiltraréis | You will infiltrate |
| Ellos / Ellas / Ustedes | infiltrarán | They / you will infiltrate |
| Vos | infiltrarás | You will infiltrate |
| Pronoun | Spanish |
|---|---|
| Yo | infiltre |
| Tú | infiltres |
| Él / Ella / Usted | infiltre |
| Nosotros / as | infiltremos |
| Vosotros / as | infiltréis |
| Ellos / Ellas / Ustedes | infiltren |
| Vos | infiltres |
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 | infiltrara | infiltrase |
| Tú | infiltraras | infiltrase |
| Él / Ella / Usted | infiltrara | infiltrase |
| Nosotros / as | infiltráramos | infiltrásemos |
| Vosotros / as | infiltrarais | infiltraseis |
| Ellos / Ellas / Ustedes | infiltraran | infiltrasen |
| Vos | infiltraras | infiltrase |
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.
