Under a misapprehension, take two days off and escape (5)
I believe the answer is:
elude
'escape' is the definition.
(I know that escape can be written as elude)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for elude that I've seen before include "Escape adroitly" , "Get round" , "Avoid; slip one's mind" , "Escape from; baffle" , "Avoid first" .)
