5. INFINITES RULE: Gaura , X-B , 2
The infinitive of a verb is considered the "base" form; it is the form that is listed in dictionaries.
RULE:
to + verb=THE INFINITE
The ‘infinites’ simply expresses the state or action denoted by the verb, to see, to play, to sing are infinites. These are called Infinites with ‘to’ or ‘to’ infinites.
But the word ‘to’ is not an essential part of the infinites. See, play, sit are also infinites. These are called Pure Infinites.
