MODAL AUXILIAR VERBS




In the English language, a modal verb is an auxiliary verb that can be used to change the grammatical mood of a sentence. The key way to identify a modal verb is by its defectiveness (they have neither participles nor infinitives).

The modal verbs in English are as follows, paired as present and preterite forms:

shall and should
will and would
may and might
can and could
mote (Archaic) and must
The following are not modal verbs but may be used for a similar purpose:

ought to and had better
used to
dare and need (Archaic use)
do
going to
Although historically referring to past time, the preterite forms have come to be used in many cases with no such meaning.
