Weak verbs are known to be verbs whose past tense are formed by adding <em>-ed, -d, or -t</em> to the base form of that verb. In weak verbs, the stem vowel does not change. While strong verbs are verbs that form the past tense or past participle by actually changing the vowel found in the present tense of that verb. In strong verbs, the stem vowel changes.
So. we can see that the distinction found between a weak verb and a strong verb is found on the basis of how the past tense of the verb is formed.
