Character gets tan over Yorkshire river (6)
I believe the answer is:
nature
'character' is the definition.
(thesaurus)
'tan over yorkshire river' is the wordplay.
'over' is a reversal indicator.
'yorkshire river' becomes 'ure' (I've seen this in other clues).
'tan' in reverse letter order is 'nat'.
'nat'+'ure'='NATURE'
'gets' is the link.
(Other definitions for nature that I've seen before include "Disposition, temperament" , "(Person's) character" , "variety" , "scientific journal" , "The physical world" .)
