[_Note to Teacher_.--This table is not to be learned now; if learned at all, it should be as practice work on strong and weak verb forms. Exercises should be given, however, to bring up sentences containing such of these conjugation forms as the pupil will find readily in literature.]
244. According to form, verbs are strong or weak.
A strong verb forms its past tense by changing the vowel of the present tense form, but adds no ending; as, _run_, _ran_; _drive_, _drove_.
A weak verb always adds an ending to the present to form the past tense, and _may_ or _may not_ change the vowel: as, _beg_, _begged_; _lay_, _laid_; _sleep_, _slept_; _catch_, _caught_.
NOTE. Some of these also have weak forms, which are in parentheses
