Throwing darts at, I figure, is going too far (7)
I believe the answer is:
drastic
'going too far' is the definition.
I can't judge whether this defines the answer.
'throwing darts at i figure' is the wordplay.
'throwing' indicates an anagram (letters get thrown around).
'at' says to put letters next to each other.
'figure' becomes 'c' (I've seen this in other clues).
'darts' is an anagram of 'drast'.
'drast'+'i'+'c'='DRASTIC'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for drastic that I've seen before include "Extreme - forceful" , "Thoroughgoing" , "Extreme - violent" , "Violent Doctor Crippen starts drinking wine" , "Uncompromising" .)
