In "The Last Verb in a Verb Phrase Must Be a Participle" I explain that substituting the past tense for the past participle in a verb phrase is such a serious grammatical error that making it is considered a sign of particular ignorance.
This error is only evident when the past tense and the past participle of the verb have different forms. Here are a few of the approximately 200 verbs in English that have irregular forms:
InfinitivePast TensePast Participle
be was been
run ran run
sing sang sung
go wentgone
choose chose chosen
break broke broken
write wrote written
swim swam swum
bite bit bitten
fall fell fallen
begin began begun
eat ate eaten
know knew known
Another gross error that is related to the misuse of the past tense for the past participle in a verb phrase is the misuse of the past participle for the past tense as the predicate of a clause. The reason why the past participle cannot be used as the predicate of a clause is explained in "Verbals: Nonfinite Verb Forms."
Here are a few examples of the past tense incorrectly used for the past participle in a verb phrase:
WRONG:
~He could have went home earlier.
~I should have ranhome for a quick lunch.
~I wish I could have sangin the talent show.
~They couldn't have came with us anyway.
~I have broke off the relationship for good.
~We have didthe best we could.
~Spring Break has alreadybegan.
CORRECTED:
~He could have gone home earlier.
~I should have run home for a quick lunch.
~I wish I could have sung in the talent show.
~They couldn't have comewith us anyway.
~I have broken off the relationship for good.
~We have done the best we could.
~Spring Break has already begun.
Here are a few examples of the other error, in which the past participle is improperly used for the past tense:
