Not all charlatans raised from birth (5)
I believe the answer is:
natal
'from birth' is the definition.
(I've seen this before)
'not all charlatans raised' is the wordplay.
'not all' indicates the answer is hidden within the clue (only some of the letters).
'raised' shows that the letters should be reversed in order (going up in a down clue).
'latan' is hidden in the letters of 'charlatans'.
'latan' in reverse letter order is 'NATAL'.
(Other definitions for natal that I've seen before include "Colony once" , "of an ass?" , "Relating to deliveries" , "Pertaining to birth" , "Like a seat" .)
