Wait in suspense? (4,2)
I believe the answer is:
hang on
'wait' is the definition.
(hanging on is a kind of waiting)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for hang on that I've seen before include "Attend closely to - just a mo' (4,2)" , "Wait a mo', or hold tightly in suspense" , "Don't let go - wait a minute" , "Hold the line" , "Don't let go - just a mo'" .)
