Detective in Georgia unwise to enter without invite (9)
I believe the answer is:
gatecrash
'enter without invite' is the definition.
I can't judge whether this defines the answer.
'detective in georgia unwise' is the wordplay.
'detective' becomes 'tec' (tec is short for detective).
'in' is an insertion indicator.
'georgia' becomes 'GA' (abbreviation).
'unwise' becomes 'rash'.
'ga'+'rash'='garash'
'tec' going within 'garash' is 'GATECRASH'.
'to' is the link.
Can you help me to learn more?
(Other definitions for gatecrash that I've seen before include "join party unofficially" , "enter without invitation" , "Try to get in for free" , "join party if not wanted" , "to do so uninvited" .)
