Upward tie? (4)
I believe the answer is:
draw
'tie?' is the definition.
('draw' can be a synonym of 'tie')
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for draw that I've seen before include "Tie - attract" , "Take in (a breath), attraction" , "Stalemate or tie" , "Make picture" , "Collect one's pay" .)
