Make warmer path with EU stimulated (4,2)
I believe the answer is:
heat up
'make warmer path with eu stimulated' is the definition.
I can't judge whether this defines the answer.
'path with eu stimulated' is the wordplay.
'with' is a charade indicator (letters next to each other).
'stimulated' indicates anagramming the letters (letters made active or stimulated).
'path'+'eu'='patheu'
'patheu' with letters rearranged gives 'HEAT UP'.
Can you help me to learn more?
(Other definitions for heat up that I've seen before include "Make more intense" , "Warm through" .)
