Old boy grabs kiss with old wife in lake (5)
I believe the answer is:
oxbow
'lake' is the definition.
(I've seen this before)
'old boy grabs kiss with old wife' is the wordplay.
'old boy' becomes 'OB' (abbreviation for a private school 'old boy').
'grabs' is an insertion indicator.
'kiss' becomes 'x' (X can represent a kiss).
'with' is a charade indicator (letters next to each other).
'old wife' becomes 'ow' (this might be a standard abbreviation of which I'm unaware).
'ob' going around 'x' is 'oxb'.
'oxb'+'ow'='OXBOW'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for oxbow that I've seen before include "Loop formed by a horseshoe bend in a river" , "Neat collar" , "U-shaped piece attached to cattle yoke" , "Small curved lake" , "Horseshoe bend in a stream" .)
