I believe the answer is:

deneb

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

But I can't explain it at all! Could you help me understand?

(Other definitions for deneb that I've seen before include "The star Alpha Cygni" , "First magnitude star in Cygnus" , "Be Ned (anag) - brightest star in Cygnus" , "Bright star in Cygnus" , "Bright star; be end (anag.)" .)

I've seen this clue in The Hindu.
