Personnel accommodate people coming up for another delivery (7)
I believe the answer is:
rebirth
'another delivery' is the definition.
'rebirth' can be an answer for 'delivery' (rebirth is a kind of delivery). I am not sure about the 'another' bit.
'personnel accommodate people coming up' is the wordplay.
'personnel' becomes 'HR' (Human Resources).
'accommodate' is an insertion indicator.
'people' becomes 'tribe' (a tribe is a group of people).
'coming up' says the letters should be written backwards (in a down clue, letters go up).
'hr' enclosing 'tribe' is 'htriber'.
'htriber' in reverse letter order is 'REBIRTH'.
'for' is the link.
Can you help me to learn more?
(Other definitions for rebirth that I've seen before include "Revival; reincarnation" , "Renascence" , "second coming" , "Spiritual renewal" , "Start of a new life?" .)
