Hotel worker with a lot of guts taking on hotel work (7)
I believe the answer is:
bellhop
'hotel worker' is the definition.
'bellhop' can be an answer for 'worker' (bellhop is a kind of worker). I'm unsure of the 'hotel' bit.
'lot of guts taking on hotel work' is the wordplay.
'lot of guts' becomes 'bell' (I can't explain this - if you can you should give a lot more credence to this answer).
'taking on' means one lot of letters go next to another.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'work' becomes 'op' (abbreviation for opus).
'bell'+'h'+'op'='BELLHOP'
'with a' acts as a link.
Can you help me to learn more?
(Other definitions for bellhop that I've seen before include "Hotel messenger" , "Hotel page" , "Baggage carrier in a hotel" , "Hotel porter (US)" , "Errand boy and luggage carrier in US hotels" .)
