Take most of this on previous day (6)
I believe the answer is:
thieve
'take' is the definition.
(thieving is a kind of taking)
'most of this on previous day' is the wordplay.
'most of' means to remove the last letter.
'on' says to put letters next to each other.
'previous day' becomes 'eve' (I've seen this before).
'this' with its last letter taken off is 'thi'.
'thi'+'eve'='THIEVE'
(Other definitions for thieve that I've seen before include "Steal things" , "Rob" , "Pilfer" , "appropriate" , "Knock off" .)
