Brazilian ready to follow team of stars (8)
I believe the answer is:
sidereal
'of stars' is the definition.
(sidereal means relating to the stars)
'brazilian ready to follow team' is the wordplay.
'brazilian ready' becomes 'real' (I can't justify this - if you can you should give a lot more credence to this answer).
'to follow' means one lot of letters go next to another (some letters go after or follow others).
'team' becomes 'side' (both can mean a sports team).
'real' put after 'side' is 'SIDEREAL'.
Can you help me to learn more?
(Other definitions for sidereal that I've seen before include "Of or measured by the stars" , "Of the stars or constellations" , "Realised (anag) -- relating to the stars" , "Relating to the distant stars" , "Relating to the constellations" .)
