Regular and Irregular verbsWith Regular and
Irregular verbs you can find the "-s" and the "-ing" form from the
base form, so it is necessary to learn only the Past and
"-ed" form for Irregular verbs.

Regular
Regular verbs have only four different forms, and you can make all of these from the Base
form.
Irregular
Some irregular verbs have five forms (e.g.
"write-writes-writing-wrote-written"), and some have only three (e.g.
"cut-cuts-cutting")
Past and -ed
For ways of doing this...
Base form
You use this in:
the Present Simple tense (but not with he/she/it)
the Imperative (Go away!/Don't ask!)
the Infinitive.
-s
...with "he", "she", and "it".
-ing Participle
...after "be" it makes the Continuous Tenses ("She is smoking").
...as an adjective (The smoking fire)
We sometimes call it also the Gerund (Smoking is bad for you) or the Present Participle.
For more details...
Past Form
...in the Past Simple tense, and sometimes in the "Subjunctive".
-ed Participle
...in the Perfect tenses (Present, Past, and Future).
..as an adjective.
...in the Passive.
had to
You can also use "must" where a past form is necessary...
