Worker with ice I included put this in radiator (10)
I believe the answer is:
antifreeze
'this in radiator' is the definition.
The answer and definition can be both substances as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'worker with ice i included' is the wordplay.
'worker' becomes 'ant' (worker is a type of ant).
'with' means one lot of letters go next to another.
'ice' becomes 'freeze' (I've seen this before).
'included' means one lot of letters goes inside another.
'ant'+'freeze'='antfreeze'
'antfreeze' enclosing 'i' is 'ANTIFREEZE'.
'put' is the link.
Can you help me to learn more?
(Other definitions for antifreeze that I've seen before include "not needed for a long time in Hell?" , "Glycol for car radiators" , "Addition to radiator" , "Liquid added to car radiator" , "Winter radiator additive" .)
