The French female performed, actress primarily trying to be posh? (2-2-2)
I believe the answer is:
la di da
'to be posh?' is the definition.
(I've seen this before)
'the french female performed actress primarily' is the wordplay.
'the french female' becomes 'la' (feminine version of 'the' in French).
'performed' becomes 'did' ('do' can be a synonym of 'perform').
'primarily' says to take the initial letters.
The initial letter of 'actress' is 'a'.
'la'+'did'+'a'='LA-DI-DA'
'trying' acts as a link.
This may not be right. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for la di da that I've seen before include "Posh" , "Affectedly pretentious" , "Conceited" , "Affectedly genteel" , "Hoity-toity" .)
