Words like smoking, walking are verbs. But we can also use them as adjectives or nouns. Compare:
- You ‘re smoking too much these days, (part of a verb)
There was a smoking cigarette end in the ashtray, (adjective)
Smoking is bad for you. (noun: subject of sentence)
When -ing forms are used as verbs or adjectives, they are called ‘present participles’. When they are more like nouns, grammars call them ‘gerunds’.
For the use of gerunds, see this section and the next two.
- An -ing form can be a subject, object or complement.

I hate packing (object)
My favourite activity is reading (complement)
The -ing form subject, object or complement is still a verb, and can have its own object.
