She makes replicas of a mere doll, perhaps (8)
I believe the answer is:
modeller
'she makes replicas' is the definition.
I can't tell whether this defines the answer.
'a mere doll perhaps' is the wordplay.
'perhaps' indicates an anagram.
'mere'+'doll'='meredoll'
'meredoll' anagrammed gives 'MODELLER'.
'of' is the link.
Can you help me to learn more?
(Other definitions for modeller that I've seen before include "Maker of small copies" , "Maker of small figures" .)
