During Monopoly, MP usually makes a mountain (7)
I believe the answer is:
olympus
'a mountain' is the definition.
(Olympus is an example)
'during monopoly mp usually' is the wordplay.
'during' indicates the answer is hidden within the clue.
'OLYMPUS' is hidden within 'monopoly mp usually'.
'makes' acts as a link.
(Other definitions for olympus that I've seen before include "Mountain home of the Greek gods" , "Mount of the ancient Greek gods" , "Dwelling place of the Greek gods" , "In Greek myth, Mount ....... was home of the Gods" , "Greece's highest mountain" .)
