Be specific about sabbatical? (5,3)
I believe the answer is:
spell out
This clue is a double definition.
'be specific about' is the first definition.
'sabbatical?' is the second definition.
(a sabbatical is a spell out or away from one's job)
(Other definitions for spell out that I've seen before include "Explain in detail" , "Temporary release from prison" , "Give precise details" , "writing letters?" .)
