Almost finished on new stove (4)
I believe the answer is:
oven
'stove' is the definition.
(I've seen this before)
'almost finished on new' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'finished' becomes 'over' ('over' can be similar in meaning to 'finished').
'on' is a charade indicator (letters next to each other).
'new' becomes 'n'.
'over' with its last letter removed is 'ove'.
'ove'+'n'='OVEN'
(Other definitions for oven that I've seen before include "You can cook in this" , "Cooking device" , "Meat is roasted in it" , "Furnace, kiln" , "kitchen item" .)
