What kind of adjective is long?

Question

I have been wondering what type of adjective long is, quantity or quality?

Answer 1

It is a qualitative adjective:

Qualitative adjectives describe the qualities of a person or thing – whether they are large or small, happy or sad, etc. This type of adjective is gradable.

For example:

• a fairly tall man

• a very boring film

• a really long holiday

• an extremely expensive car

(ODO)

A quantitative adjective modifies a noun by indicating a number/quantity It can be either cardinal or ordinal number.
