Lapse from close-catcher (4)
I believe the answer is:
slip
'lapse' is the definition.
(thesaurus)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for slip that I've seen before include "Slight error" , "Lose footing as on banana skin" , "Mistake -- small piece of paper" , "failure" , "Slight mistake" .)
