Quote by DirtyDazza
A gerund is a verb with ing at the end that acts as a noun.
Example:
Smoking is bad for you.
In this example the verb "smoke" has ing at the end and acts as the subject of the clause and is therefore a noun.
Running is good exercise.
Sucking on tits makes me happy.
The third example is not the gerund, as this is simply the present participle progressive of to suck.
