Irish girl learning to gatecrash parties (7)
I believe the answer is:
dolores
'irish girl' is the definition.
'Dolores' can be an answer for 'girl'. I am not sure about the 'irish' bit.
'learning to gatecrash parties' is the wordplay.
'learning' becomes 'lore' (both can mean tradition or knowledge).
'to gatecrash' means one lot of letters goes inside another (inserted letters gatecrash their way in).
'parties' becomes 'dos' (do is a kind of party).
'lore' going into 'dos' is 'DOLORES'.
Can you help me to learn more?
(Other definitions for dolores that I've seen before include "Female" , "Old sore about girl" , "Lady" .)
