Hot drink with cinnamon, e.g., using only a bit (5)
I believe the answer is:
negus
'hot drink' is the definition.
(I've seen this before)
'cinnamon e g using only a bit' is the wordplay.
'only a bit' says the answer is hidden in the clue (I've seen 'only a bit of' mean this).
'NEGUS' is hidden in the letters of 'cinnamon e g using'.
'with' acts as a link.
(Other definitions for negus that I've seen before include "Hot wine" , "Title of Emperor of Ethiopia" , "Ethiopian emperor (hist.)" , "Hot fortified drink" , "Hot, spiced alcoholic drink" .)
