A flipping angry look upset one under pressure? (7)
I believe the answer is:
'one under pressure?' is the definition.
The answer and definition can be both types of natural phenomena as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'a flipping angry look upset' is the wordplay.
'flipping' shows that the letters should be reversed in order.
'angry' becomes 'sore' (similar in meaning).
'look' becomes 'lo'.
'upset' says the letters should be written in reverse.
'sore' backwards is 'eros'.
'lo' backwards is 'ol'.
Can you help me to learn more?
(Other definitions for aerosol that I've seen before include "Liquid in a container under pressure", "Substance sealed in container and released as fine spray", "A suspension", "See 17 down [CONTAINER]: under pressure", "It dispenses liquid in a fine spray".)
