The verbs of the following list also are irregular; but as they lack one
or more of the principal parts, they are called defective verbs.

_Defective Verbs_

Present Past Present Past

can could ought .....
may might ..... quoth
must ..... beware .....
shall should methinks methought
will would

All the participles are wanting in defective verbs.

The verb _ought_, when used to express past duty or obligation, is
followed by what is called the perfect infinitive--a use peculiar to
itself because _ought_ has no past form.

_Example:_ I ought _to have gone_ yesterday.

Other verbs expressing past time are used in the past tense followed by
the root infinitive.

_Example:_ I intended _to go_ yesterday.
