Van of Amazon figure in old African region before delivery (9)
I believe the answer is:
antenatal
'before delivery' is the definition.
(I've seen this before)
'van of amazon figure in old african region' is the wordplay.
'van of' indicates taking the first letters (van can mean the front part of something).
'figure' becomes 'ten' (I've seen this in other clues).
'in' indicates putting letters inside.
'old african region' becomes 'Natal' (historical British colony in Africa).
The first letter of 'amazon' is 'a'.
'ten' going inside 'natal' is 'ntenatal'.
'a'+'ntenatal'='ANTENATAL'
(Other definitions for antenatal that I've seen before include "Check before delivery" , "prior to delivery" , "Pre-birth" , "Prior to birth" , "Relating to the care of women during pregnancy" .)
