Base trickery takes in husband for now (9)
I believe the answer is:
meanwhile
'for now' is the definition.
(both can mean presently)
'base trickery takes in husband' is the wordplay.
'base' becomes 'mean' (synonyms).
'trickery' becomes 'wile' (wile can mean a trick or scheme).
'takes in' means one lot of letters goes inside another.
'husband' becomes 'h'.
'wile' enclosing 'h' is 'while'.
'mean'+'while'='MEANWHILE'
(Other definitions for meanwhile that I've seen before include "For the moment" , "On the other hand" , "In the intervening time" , "In the interim" , "simultaneously" .)
