IT expert dressed in white chiefly (6)
I believe the answer is:
techie
'it expert' is the definition.
(I've seen this before)
'in white chiefly' is the wordplay.
'in' indicates the answer is hidden within the clue.
'TECHIE' can be found hidden inside 'white chiefly'.
'dressed' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for techie that I've seen before include "Expert in some practical science" , "computer expert" , "PC expert" , "IT whizz" .)
