Drowsy Yankee strips in reverse? (6)
I believe the answer is:
sleepy
'drowsy' is the definition.
(I've seen this before)
'yankee strips in reverse?' is the wordplay.
'yankee' becomes 'Y' (phonetic alphabet: alpha, bravo, charlie etc.).
'strips' becomes 'peels' (peeling is a kind of stripping).
'in reverse?' is a reversal indicator (I've seen 'in reverse' mean this).
'y'+'peels'='ypeels'
'ypeels' back-to-front is 'SLEEPY'.
(Other definitions for sleepy that I've seen before include "Drowsy; indolent" , "Dwarf" , "Drowsy - without excitement" , "needing a rest" , "Is inactive" .)
