B1 Spanish GrammarInfinitive vs Gerund
Learn when to use the infinitive (hablar, comer) versus the gerund (hablando, comiendo) in Spanish. Unlike English, Spanish uses the infinitive far more often. Master verb combinations with prepositions and understand the progressive tenses with estar + gerund.
1Using the Infinitive
The infinitive is the default verb form after prepositions (sin hablar, para comer, al llegar), after most verbs (quiero ir, puedo hacerlo), and as a noun (Fumar es malo). Unlike English, Spanish never uses the gerund after prepositions.
Infinitive After Prepositions
| Preposition | Spanish | English (uses -ing) |
|---|---|---|
| sin | sin decir nada | without saying anything |
| para | para aprender | for learning / to learn |
| después de | después de comer | after eating |
| antes de | antes de salir | before leaving |
| al | al ver eso | upon seeing that |
Examples
Salió sin decir adiós.
He left without saying goodbye.
sin + infinitive, NOT sin diciendo
Estudia para aprobar el examen.
She studies to pass the exam.
para + infinitive
Al llegar a casa, me dormÃ.
Upon arriving home, I fell asleep.
al + infinitive = upon -ing
Después de cenar, vemos la tele.
After eating dinner, we watch TV.
después de + infinitive
2The Gerund (Gerundio)
Form the gerund with -ando (ar verbs) or -iendo (er/ir verbs). Stem-changing verbs change in the gerund: dormir→durmiendo, sentir→sintiendo, pedir→pidiendo. Use the gerund with estar for progressive tenses and to show an action happening simultaneously.
Gerund Formation
| Verb Type | Infinitive | Gerund |
|---|---|---|
| -ar verbs | hablar | hablando |
| -er verbs | comer | comiendo |
| -ir verbs | vivir | viviendo |
| stem change (o→u) | dormir | durmiendo |
| stem change (e→i) | pedir | pidiendo |
| y insertion | leer | leyendo |
Examples
Estoy estudiando español.
I am studying Spanish.
estar + gerund = present progressive
Llegó corriendo.
He arrived running.
manner: how the action was done
Pasó la tarde leyendo.
She spent the afternoon reading.
duration with pasar/llevar
Siguió hablando sin parar.
He kept talking non-stop.
seguir + gerund = keep -ing
3Progressive Tenses with Estar
Estar + gerund creates progressive tenses: estoy comiendo (I am eating), estaba durmiendo (I was sleeping), estaré trabajando (I will be working). Use progressives for actions happening at a specific moment. Spanish progressives are used less than English - simple tenses often suffice.
Progressive Tense Forms
| Tense | Estar | Example |
|---|---|---|
| Present | estoy/estás/está... | Estoy comiendo |
| Imperfect | estaba/estabas... | Estaba durmiendo |
| Preterite | estuve/estuviste... | Estuve esperando |
| Future | estaré/estarás... | Estaré trabajando |
Examples
Estoy viendo una pelÃcula.
I'm watching a movie.
present progressive
Estaban cenando cuando llamé.
They were having dinner when I called.
past progressive
Mañana a esta hora estaré volando.
Tomorrow at this time I'll be flying.
future progressive
Estuve esperando dos horas.
I was waiting for two hours.
completed action that took time
4Verbs with Infinitive vs Gerund
Most Spanish verbs take an infinitive: querer, poder, deber, necesitar, esperar, preferir, intentar, decidir, saber, prometer. Only a few use the gerund: seguir/continuar (keep doing), llevar (have been doing), ir (gradually), acabar/terminar (end up), estar.
