Relative travels around globe (3)
I believe the answer is:
orb
'globe' is the definition.
(synonyms)
'relative travels around' is the wordplay.
'relative' becomes 'bro' (short for brother).
'travels around' is a reversal indicator (turned around).
'bro' backwards is 'ORB'.
(Other definitions for orb that I've seen before include "Royal sphere (paired with 13 across)" , "Ceremonial globe carried by a monarch" , "Item of insignia" , "component of royal regalia" , "A sphere or globe" .)
