Main or Principal Verbs : Words like 'sing', 'drink', 'weep', 'speak' and so on are main verbs.
We add 'd', 'ed' or 'ing' at the end of such verbs to form new verbs. The base form of the
verbs or the principal verb may be changed according to other words in the sentence.

Examples : speak spoke, break broken

play played, drink drinking

Sometimes, we change the base form of the verb also.

Strong and Weak Verbs :

Verbs are divided into two classes :

• Weak Verbs • Strong Verbs

Weak verbs form their past tense by adding '-ed', or '-d' or '-t' to the present tense.

Examples : talk – talked, send – sent

Strong verbs form their past tense by merely changing the inside vowel(s) of their present
tense.

Examples : awake – awoke, fall – fell
