Ungradable adjectives

Adjectives are words like "small", "green", "old", "nice", "healthy", etc. which describe the characteristics of things.

Most adjectives can be intensified with "very":

• very small
• very old

But there are certain adjectives that don't fit well with intensifiers like "very". These ungradable adjectives are
already complete or very strong on their own. When you try to use "very" with one of these , it sounds wrong. Here are some examples of combinations that sound strange:

• very terrible
• very freezing
• very married

When it comes to intensifiers other than "very", it's a little more complicated. These are OK:

• completely terrible
• quite terrible
• absolutely freezing

But these are strange:

• absolutely married (because a person is either married or not)
• a bit freezing (because "freezing" is very extreme, so the meaning doesn't fit with "a bit")
