Supporting English hotel that's in difficulty (6)
I believe the answer is:
behind
'supporting' is the definition.
(I've seen this in another clue)
'english hotel that's in difficulty' is the wordplay.
'english' becomes 'E' (abbreviation).
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'that's in' means one lot of letters goes inside another.
'difficulty' becomes 'bind' (bind is a kind of difficulty).
'e'+'h'='eh'
'eh' inserted within 'bind' is 'BEHIND'.
(Other definitions for behind that I've seen before include "Rear - losing" , "Following - trailing - supporting" , "Taking place in secret" , "Serving time" , "In arrears; guiding" .)
