Keep making a hotel out of date (4)
I believe the answer is:
hold
'keep' is the definition.
(holding is a kind of keeping)
'a hotel out of date' is the wordplay.
'a hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'out of date' becomes 'old' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'h'+'old'='HOLD'
'making' is the link.
Can you help me to learn more?
(Other definitions for hold that I've seen before include "Nelson?" , "Keep in one's grasp" , "Grasp; clutch" , "Ship's storage area" , "Cargo area of ship" .)
