Hold spellbound setting up hotel on square in Ulster port (7)
I believe the answer is:
enthral
'hold spellbound' is the definition.
(I've seen this before)
'up hotel on square in ulster port' is the wordplay.
I cannot really see how this works, but
'hotel' could be 'h' (phonetic alphabet: alpha, bravo, charlie etc.) and 'h' is found within the answer.
'square' could be 't' (a T-Square is a technical drawing instrument) and 't' is found in the answer.
'port' could be 'l' and 'l' is located in the answer.
This explanation may well be incorrect...
'setting' acts as a link.
Can you help me to learn more?
(Other definitions for enthral that I've seen before include "Hold captive" , "Hold spellbound" , "Totally fascinate" , "Entrance" , "Captivate" .)
