Give someone an inkling of popular, short bit of advice given to wife (8)
I believe the answer is:
intimate
'give someone' is the definition.
'intimate' can be an answer for 'someone' (intimate is a kind of someone). I'm not certain of the 'give' bit.
'an inkling of popular short bit of advice given to wife' is the wordplay.
'an inkling of popular short bit of advice' becomes 'inti' (I can't justify this - if you can you should give a lot more credence to this answer).
'given to' says to put letters next to each other.
'wife' becomes 'mate'.
'inti'+'mate'='INTIMATE'
Can you help me to learn more?
(Other definitions for intimate that I've seen before include "Private and personal like close acquaintanceship" , "Close acquaintance" , "Friendly" , "Personal - hint - friend" , "Tip off" .)
