Civil Service accepting single copies? (6)
I believe the answer is:
clones
'copies?' is the definition.
(I know this)
'civil service accepting single' is the wordplay.
'civil service' becomes 'CS' (abbreviation).
'accepting' is an insertion indicator (inserted letters are accepted).
'single' becomes 'lone' (synonyms).
'cs' placed around 'lone' is 'CLONES'.
(Other definitions for clones that I've seen before include "Genetically identical copies" , "Genetically identical organisms derived from a single cell" , "Organisms reproduced asexually" , "Identical copies of cells" , "Identical copies produced by genetic engineering" .)
