Phone left in shady place (6)
I believe the answer is:
blower
'phone' is the definition.
(informal term for telephone)
'left in shady place' is the wordplay.
'left' becomes 'l' (common abbreviation).
'in' is an insertion indicator.
'shady place' becomes 'bower' (I've seen this before).
'l' inserted into 'bower' is 'BLOWER'.
(Other definitions for blower that I've seen before include "Speaking-tube" , "One producing current" , "Air mover; telephone" , "Telephone (informal)" , "Fan - phone" .)
