Betrothed person's lovemaking halted around noon (8)
I believe the answer is:
intended
'betrothed person's' is the definition.
'intended' can be an answer for 'betrothed' (thesaurus). I am unsure of the 'person's' bit.
'lovemaking halted around noon' is the wordplay.
'lovemaking' becomes 'it' (both are euphemisms for sex).
'halted' becomes 'ended' ('end' can be a synonym of 'halt').
'around' means one lot of letters goes inside another.
'noon' becomes 'n' (abbreviation for noon).
'it'+'ended'='itended'
'itended' going around 'n' is 'INTENDED'.
Can you help me to learn more?
(Other definitions for intended that I've seen before include "Person engaged" , "no mistake!" , "Fianc(e) - proposed" , "Fiancé (e) - on purpose" , "Fiancee (colloq.)" .)
