Grammar revision: regular and irregular verbs
Regular verbs
The past simple and past participle of regular verbs end in —ed.
Describe-described-described, include-included-included
Irregular verbs
Irregular verbs do not follow this rule. For some irregulars, all the three forms are the same.
Hit-hit-hit, let-let-let, put-put-put
For other irregular verbs, the past simple is the same as the past participle.
Tell-told-told, make-made-made, catch-caught-caught
With some other verbs, the three forms are different.
Write-wrote-written, do-did-done, show-showed-shown
There are some verbs that can be regular or irregular.
Burn-burned-burned or burn-burnt-burnt
Dream-dreamed-dreamed or dream-dreamt – dreamt
It is more usual to use the irregular forms in British English.
We use the past participle for making the perfect tenses and the passive forms.
