Book miners once found outside a hotel (5)
I believe the answer is:
nahum
'book' is the definition.
(I've seen this before)
'miners once found outside a hotel' is the wordplay.
'miners once' becomes 'num' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'found outside' means one lot of letters goes inside another.
'hotel' becomes 'h' (phonetic alphabet).
'a'+'h'='ah'
'num' going around 'ah' is 'NAHUM'.
Can you help me to learn more?
(Other definitions for nahum that I've seen before include "Destruction-of-Nineveh prophet" , "OT book and prophet who foretold the fall of Nineveh" , "Old Hebrew prophet" , "Minor prophet" , "Prophet's book" .)
