Printing workers - the kind used by crossword compilers! (11)
I believe the answer is:
typesetters
'printing workers' is the definition.
'typesetters' can be an answer for 'workers' (typesetter is a kind of worker). I'm unsure of the 'printing' bit.
'kind used by crossword compilers' is the wordplay.
'kind' becomes 'type' (type is a kind of kind).
'used by' is a charade indicator (letters next to each other).
'crossword compilers' becomes 'setters' (people who set crosswords).
'type'+'setters'='TYPESETTERS'
'the' acts as a link.
Can you help me to learn more?
(Another definition for typesetters that I've seen is " Bookmakers possibly".)
