What is the meaning of suffix ign?

The suffix "-ign" is not a common suffix in English. It is likely you are thinking of "-ing," which is a very common suffix in English.

"-ing" is a suffix that forms the present participle of a verb. For example:

* walk + ing = walking

* eat + ing = eating

The present participle can function as:

* A verb: He is walking down the street.

* A noun: The walking was slow.
