Optional is adjective so what is the verb?

[Mosu]

Hi there,

I like this forum and the website as well. I'm a beginner in English. Would you help me to find the other part of speech for the following:

Noun Verb Adj. Adv.

Opposite x

Option Optional x

x x unobtrusive

various x

And if you know a website can help me to find the other part of speech for any English word.

Thanks in advanced

Mosu

Adverb:A word that modifies a verb, an adjective, or another adverb or the word which supports verb or adjective e.g My father is really(Adverb;supported the adjective which is proud) proud of me or He tried to do well(adverb which supported verb which is tried)

Thanks Hassan,

What a great explination!

My question is about how to find the other part of speech for a word. Like build is a verb, building is noun and builder is a person name.

I hope you get my point.
