Suddenly take off pound, cutting price (4)
I believe the answer is:
flee
'suddenly take off' is the definition.
I can't tell whether this definition defines the answer.
'pound cutting price' is the wordplay.
'pound' becomes 'L' (the pound sign is based on an L).
'cutting' means one lot of letters goes inside another (some letters cut their way into a word).
'price' becomes 'fee' (I've seen this before).
'l' placed inside 'fee' is 'FLEE'.
Can you help me to learn more?
(Other definitions for flee that I've seen before include "Run quickly away" , "Do a runner" , "Take to one's heels" , "rush" , "Maybe escape" .)
