Question

What is a verb infinitive and what does is mean to conjugate a verb?

Answer 1

The infinitive is the base form of a verb. In English, the infinitive is marked by placing a "to" before the verb, for example:

drink - this is just a regular verb

to drink - this is the infinitive of the verb

To conjugate a verb means to change its form to express tense, mood, person and so on. Verbs change as they are used with different people and different time.

With people:

I drink

You drink

He/She/It drinks

We drink

You drink

They drink

With time:

I drank

You have drunk

He/She/It had drunk

We/You/They will drink

In Spanish (tho you may not need this), the infinitive is marked by three endings + the stem of the verb:

1. AR: hablar, cantar

2. ER: hacer, querer

3. IR: decir, venir

And the conjugation is much more complicated.
