Let's learn about Regular and Irregular Verbs

The spellings of English verbs don't follow any fixed pattern when their forms change.

Even then there are verbs that can be made 'past' (simple) and 'past participle' by simply adding 'd' or 'ed' to the base form. You need not learn by heart their forms.

E.g. Suggest (root form / base form/ Present form), suggested (Simple Past) suggested (Past Participle)

The above type of verbs is known as Regular Verb.

But the verbs that do not follow the above rule are known as Irregular Verbs.
They are so irregular that you always run the risk of misspelling them unless you learn them by heart:

E.g. Go, Went, Gone
Put, Put, Put
Write, Wrote, Written

I will post more examples later.
