Verb + (preposition) + infinitive
Some conjugated verbs are followed by a preposition plus an infinitive. Unfortunately, there is no set
rule to know which are followed by prepositions. You learn these by using them. Below is a list of
some verbs followed by prepositions plus infinitives
‘ir’ a + inf
going to (do something)
‘soñar’ con + inf
to dream about (doing something)
‘acabar’ de + inf
to have just (done something)
‘comenzar’ a + inf
to start (to do something)
‘empezar’ a + inf
to start (to do something)
‘insistir’ en + inf
to insist on (doing something)
‘enseñar’ a + inf
To teach someone (to do something)
‘ponerse’ a + inf
to begin (to do something)
‘dejar’ de + inf
To stop (doing something)
‘ayudar’ a + inf
To help someone (to do something)
‘tratar’ de + inf.
To try (to do something)
‘Tener’ que + inf
to have (to do something)
Other verbs that you’ve used in the past do not require a preposition, but are instead simply
followed by the infinitive.
‘Pensar’ + inf.
to plan (to do something)
‘Soler’ (ue) + inf
to usually (do something)
‘Necesitar’ + inf
To need (to do something)
‘Querer’ + inf
To want (to do something)
‘Deber’ + inf
To ought (to do something)
Remember, even if the verb is usually followed by the subjunctive, if the subject DOES NOT
CHANGE we simply use the infinitive.
‘Esperar’ + inf
To hope (to do something)
ex: Espero que puedas venir a a la fiesta
I hope that you can come to the party.
We have a change in subj. so we use the subjunctive
Ex2: Espero venir a la fiesta.
I hope to come to the party.
We don’t have a change in subj. so we use the inf.
