Coincide with old father putting up with revolution (7)
I believe the answer is:
overlap
'coincide with old father' is the definition.
'overlap' can be an answer for 'coincide' (I've seen this before). I am not sure about the 'with old father' bit.
'up with revolution' is the wordplay.
'up' becomes 'over'.
'with' means one lot of letters go next to another.
'revolution' becomes 'lap' (I've seen this before).
'over'+'lap'='OVERLAP'
'putting' acts as a link.
Can you help me to learn more?
(Other definitions for overlap that I've seen before include "Partly hide" , "Project" , "have something in common" , "Put extra cover on" , "Partly coincide in time, area etc" .)
