DEFECTIVE VERBS are those which are used only in some of the moods and
tenses.
The principal of them are these.
_Pres. Tense. Imperf. Tense. Perfect or Passive Participle
is wanting_.
May, might. ------------
Can, could. ------------
Will, would. ------------
Shall, should. ------------
Must, must. ------------
Ought, ought. ------------
----- quoth. ------------
NOTE. _Must_ and _ought_ are not varied. _Ought_ and _quoth_ are
never used as auxiliaries. _Ought_ is always followed by a verb in
the infinitive mood, which verb determines its tenses. _Ought_ is in
the _present_ tense when the infinitive following it is in the
present; as, "He _ought_ to do it;" and _ought_ is in the
_imperfect_ tense when followed by the perfect of the infinitive;
as, "He _ought_ to have done it."

pursue the _systematic order_, and to conjugate every verb until you
