Fighter with precipitate manoeuvre, ultimately leading to painful episode (8)
I believe the answer is:
migraine
'painful episode' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'fighter with precipitate manoeuvre ultimately' is the wordplay.
'fighter' becomes 'mig' (fighter jet produced by Russian company MiG).
'with' means one lot of letters go next to another.
'precipitate' becomes 'rain' (raining is a kind of precipitating).
'ultimately' says to take the final letters.
The last letter of 'manoeuvre' is 'e'.
'mig'+'rain'+'e'='MIGRAINE'
'leading to' acts as a link.
Can you help me to learn more?
(Other definitions for migraine that I've seen before include "misery in capital area" , "From mare gin I get a severe headache" , "may give one a sort of headache" , "Thumping headache" , "It brings severe headache" .)
