Why are things often "very tasty", but rarely "very delicious"
Solution 1:
Intensifiers with strong adjectives:
Strong adjectives are words like:
enormous, huge = very big
tiny = very small
brilliant = very clever
awful; terrible; disgusting; dreadful = very bad
certain = very sure
excellent; perfect; ideal; wonderful; splendid = very good
delicious = very tasty
- We do not normally use very with these adjectives. We do not say something is "very enormous" or someone is "very brilliant".
