Answer 1

An infinitive is an unconjugated verb; it ends in -ar, -er or -ir. You must have at least one conjugated verb per clause--this is true in most every language. Usually in Spanish (as in English) the first verb of the clause is conjugated; if there is a verb directly afterward, it is left as an infinitive.
