Fundir is a Spanish verb which translates into English as “to smelt, fuse”.
Below are all of the conjugations for fundir 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 smelt, fuse |
|---|---|
| Spanish Infinitive | fundir |
The gerund (gerundio) is used with the continuous tenses, e.g. present continuous (está fundiendo) and past continuous (estaba fundiendo). The easiest way to think of it is the equivalent of english’s -ing form (e.g. smelted).
The past participle (participio) is used with perfect tense ‘haber’ verbs, e.g. he smelted and hubiera smelted. These are the equivalent of English’s ‘have’ (e.g. have smelting).
| Gerundio / Gerund | fundiendo |
|---|---|
| Participio / Past Participle | smelted |
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 smelt” or “they smelt”.
| Pronoun | Spanish |
|---|---|
| Yo | fundo |
| Tú | fundes |
| Él / Ella / Usted | funde |
| Nosotros / as | fundimos |
| Vosotros / as | fundís |
| Ellos / Ellas / Ustedes | funden |
| Vos | fundís |
Your simple past tense, e.g. “I smelt” or “she smelt” 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 | fundí | I smelt |
| Tú | fundiste | You smelt |
| Él / Ella / Usted | fundió | He / she / you smelt |
| Nosotros / as | fundimos | We smelt |
| Vosotros / as | fundisteis | You smelt |
| Ellos / Ellas / Ustedes | fundieron | They / you smelt |
| Vos | fundiste | You smelt |
The pretérito imperfecto roughly translates as “I was smelted” or “she was smelted” 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 | fundía | I was smelted |
| Tú | fundías | You were smelted |
| Él / Ella / Usted | fundía | He was / she was / you were smelted |
| Nosotros / as | fundíamos | We were smelted |
| Vosotros / as | fundíais | You were smelted |
| Ellos / Ellas / Ustedes | fundían | They / you were smelted |
| Vos | fundías | You were smelted |
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 smelting” and “she has smelting”.
| Pronoun | Spanish | English |
|---|---|---|
| Yo | he smelted | I have smelting |
| Tú | has smelted | You have smelting |
| Él / Ella / Usted | ha smelted | He has / she has / you have smelting |
| Nosotros / as | hemos smelted | We have smelting |
| Vosotros / as | habéis smelted | You have smelting |
| Ellos / Ellas / Ustedes | han smelted | They / you have smelting |
| Vos | has smelted | You have smelting |
The conditional is used in place of the English modal verb “would”, i.e. “I would smelt” or “she would smelt”. It can be used to talk about hypothetical situations.
| Pronoun | Spanish | Englush |
|---|---|---|
| Yo | fundiría | I would smelt |
| Tú | fundirías | You would smelt |
| Él / Ella / Usted | fundiría | He / she / you would smelt |
| Nosotros / as | fundiríamos | We would smelt |
| Vosotros / as | fundiríais | You would smelt |
| Ellos / Ellas / Ustedes | fundirían | They / you would smelt |
| Vos | fundirías | You would smelt |
The future tense, simply put, replaces the English modal verb “will” – i.e. “I will smelt” or “they will smelt”.
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 fundir” means “They are going to smelt”.
| Pronoun | Spanish | English |
|---|---|---|
| Yo | fundiré | I will smelt |
| Tú | fundirás | You will smelt |

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 | fundiera | fundiese |
| Tú | fundieras | fundiese |
| Él / Ella / Usted | fundiera | fundiese |
| Nosotros / as | fundiéramos | fundiésemos |
| Vosotros / as | fundierais | fundieseis |
| Ellos / Ellas / Ustedes | fundieran | fundiesen |
| Vos | fundieras | fundiese |
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.

| Yo | fundiere |
| Tú | fundieres |
| Él / Ella / Usted | fundiera |
