Egg-maker mixes beer with fag (7)
I believe the answer is:
faberge
'egg-maker' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'mixes beer with fag' is the wordplay.
'mixes' indicates an anagram.
'with' means one lot of letters go next to another.
'beer'+'fag'='beerfag'
'beerfag' anagrammed gives 'FABERGE'.
Can you help me to learn more?
(Other definitions for faberge that I've seen before include "Russian goldsmith known for his jewelled Easter eggs" , "fine Russian jewellery?" , "Renowned jeweller" .)
