=Principal Parts=

=54. Use the correct form of the past tense and past participle.= Avoid
_come_, _done_, _bursted_, _knowed_, _says_ for the past tense; and
[_had_] _eat_, [_had_] _froze_, [_have_] _ran_, [_has_] _went_, [_has_]
_wrote_, [_are_] _suppose_ for the past participle. Memorize the
principal parts of difficult verbs. The principal parts are the present
tense, the past tense, and the past participle. A good way to recall
these is to repeat the formula: Today I _sing_; yesterday I _sang_;
often in the past I have _sung_. The principal parts of _sing_ are
_sing_, _sang_, _sung_. A list of difficult verbs is given below.
