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 don't 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' says to put letters next to each other.
'precipitate' becomes 'rain' (raining is a kind of precipitating).
'ultimately' indicates one should take the final letters.
The last letter of 'manoeuvre' is 'e'.
'mig'+'rain'+'e'='MIGRAINE'
'leading to' is the 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" .)
