Many words in English have four different forms; verb, noun, adjective and adverb. A large number of words have the four forms; some do not.

For example some recently-coined words such as ‘avatar’, ‘captcha’ or ‘selfie’ only exist as nouns.
Others, such as the noun ‘fun’, have no verb or adverb form.
The verb ‘sing’ has a noun form ‘singer’ but no adjective or adverb.
Sometimes several adjectives can be formed from a verb by adding suffixes such as ‘–able,’ ‘-ed,’ and ‘–ing’.

Here are some words with all four forms:
