Question

How can we recognize an infinitive in Spanish?

Answer 1

check out this reference article on infinitives

Answer 2

If it ends in -ir, -ar, -er. Also look at the context of the sentence.

Answer 3

Recognizing a word ending in "-ar", "-er or "-ir" is a good first step. Other parts of speech can also have those endings but as a first approximation, that's not bad.

Answer 4

Infinative verbs finish in ar, er or ir e.g. amar, hacer and venir to love, do and come.

Answer 5

I would consider any un-conjugated verb ending in -ar -er -ir to be in its infinitive form.
