Compel one to enter rebuilt Globe (6)
I believe the answer is:
oblige
'compel' is the definition.
(I know that compel can be written as oblige)
'one to enter rebuilt globe' is the wordplay.
'one' becomes 'I' (Roman numeral).
'to enter' means one lot of letters goes inside another.
'rebuilt' is an anagram indicator.
'globe' anagrammed gives 'oblge'.
'i' inserted inside 'oblge' is 'OBLIGE'.
(Other definitions for oblige that I've seen before include "Do something as a favour to (someone)" , "Bind morally or legally" , "Hold in debt" , "Put oneself out for" , "Perform a service for (someone)" .)
