Answer 2

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.

But lie and lay seem to give people more difficulty than do all the other irregular verbs combined. Here's why: The past tense form of lie is lay, so it's indistinguishable from lay in the present tense except in usage. (Sit and set, probably the irregular verbs that give people the most trouble next to lie and lay, for example, have no parts in common. It's sit, sat and sat but set, set, set.)

The principal parts (most-common verb forms) of lie are:

lie (present,) lay (past) and lain (past participle).

The principal parts of lay are:

lay (present), laid (past) and laid (past participle).
