Escape is fast with little time wasted (4)
I believe the answer is:
flee
'escape' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for flee that I've seen before include "Do a runner" , "Take flight" , "Cut and run" , "Turn tail" , "Abscond" .)
