In general, irregular verbs are troublesome to learn. Regular verbs create their past and past participle forms by adding “d” or “ed” to the stem of their infinitives (love, loved, loved), but irregular verbs create past and past participle forms by altering their stems in unpredictable ways.       A number of common irregular verbs give people trouble, particularly: dive, drown, fly, hang, lead, prove, sit, set and shrink.
