British eggs seeing upturn? Excellent! (5)
I believe the answer is:
bravo
'british eggs seeing upturn? excellent' is the definition.
I can't judge whether this definition defines the answer.
'british eggs seeing upturn?' is the wordplay.
'british' becomes 'br' (abbreviation for British).
'eggs' becomes 'ova' (term for egg cells).
'seeing upturn?' is a reversal indicator (in a down clue, letters go up).
'ova' backwards is 'avo'.
'br'+'avo'='BRAVO'
Can you help me to learn more?
(Other definitions for bravo that I've seen before include "B in radio communications" , "Radio code word for B" , "Exclamation of approval" , "West Indian cricket captain" , "congratulations" .)
