He may call for you at an American hotel (7)
I believe the answer is:
bellhop
'he' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'call for you at an american hotel' is the wordplay.
I cannot quite understand how this works, but
'call' could be 'bell' (I've seen this before) and 'bell' is located in the answer.
'hotel' could be 'h' (phonetic alphabet: alpha, bravo, charlie etc.) and 'h' is present in the answer.
The remaining letters 'op' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'may' acts as a link.
Can you help me to learn more?
(Other definitions for bellhop that I've seen before include "Baggage carrier in a hotel" , "Hotel porter (US)" , "Errand boy and luggage carrier around hotels" , "Errand boy and luggage carrier in US hotels" , "Hotel page" .)
