Word such as this put off Pitman (10)
I believe the answer is:
determiner
'word' is the definition.
(determiner is a kind of word)
'this put off pitman' is the wordplay.
'this put off' becomes 'deter' (both can mean to discourage).
'pitman' becomes 'miner' (I've seen this in another clue).
'deter'+'miner'='DETERMINER'
'such as' is the link.
(Other definitions for determiner that I've seen before include "Settler" , "thing that makes the difference?" , "Perhaps that" .)
