Streams revealed by Scottish poet (5)
I believe the answer is:
burns
'scottish poet' is the definition.
(Robert Burns)
I don't understand how the rest of the clue works.
(Other definitions for burns that I've seen before include "feels strong emotion" , "Scots poet" , "Cremates -- Scottish poet, d.1796" , "What Tyger does for Blake" , "Tam o' Shanter poet, d. 1796" .)
