Saint with South African money getting thread (6)
I believe the answer is:
strand
'thread' is the definition.
(strand of material)
'saint with south african money' is the wordplay.
'saint' becomes 'st' (abbreviation).
'with' says to put letters next to each other.
'south african money' becomes 'rand' (currency of South Africa).
'st'+'rand'='STRAND'
'getting' is the link.
(Other definitions for strand that I've seen before include "Leave helpless - length of fibre" , "Lock of hair" , "Beach or single hair" , "Ply" , "Thread - London street" .)
