Starting a relationship primarily around sex: strings attached to this? (5)
I believe the answer is:
sitar
'strings attached to this?' is the definition.
(sitar is a type of stringed instrument)
'starting a relationship primarily around sex' is the wordplay.
'starting' becomes 's' (this could be a standard abbreviation which I don't know about).
'primarily' says to take the initial letters.
'around' is an insertion indicator.
'sex' becomes 'it' (a common euphemism).
The initial letter of 'relationship' is 'r'.
's'+'a'+'r'='sar'
'sar' enclosing 'it' is 'SITAR'.
Can you help me to learn more?
(Other definitions for sitar that I've seen before include "Plucked instrument" , "Lasting from morning to night" , "instrument out east" , "Long-necked musical instrument of India" , "Indian musical instrument like long-necked lute" .)
