I'm a little stuck... Click here to teach me more about this clue!

'governor abroad somewhat' is the definition.
I can't tell whether this defines the answer.

'open to spin' is the wordplay.
'open' becomes 'ajar' ('ajar' can be similar in meaning to 'open').
'to spin' is a reversal indicator.
'ajar' backwards is 'RAJA'.

Can you help me to learn more?

(Other definitions for raja that I've seen before include "Asian prince or king" , "sovereign" , "Indian prince or king" , "High Indian position" , "Prominent Indian" .)
