Wife agreed to return hybrid (5)
I believe the answer is:
yakow
'hybrid' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'wife agreed to return' is the wordplay.
'wife' becomes 'w' (abbreviation).
'agreed' becomes 'okay' (I've seen this in another clue).
'to return' is a reversal indicator.
'w'+'okay'='wokay'
'wokay' reversed gives 'YAKOW'.
Can you help me to learn more?
(Other definitions for yakow that I've seen before include "Yak/Cow crossbreed (guess!)" , "cross" .)
