Brief class getting award at university from key contributor to The Office (6)
I believe the answer is:
typist
'university from key contributor to the office' is the definition.
I can't tell whether this definition defines the answer.
'brief class getting award at' is the wordplay.
'brief' means to remove the last letter (a shorter or briefer version of the word).
'class' becomes 'type' (both can mean a variety or kind).
'getting' is a charade indicator (letters next to each other).
'award at' becomes 'ist' (I can't explain this - if you can you should believe this answer much more).
'type' with its final letter taken off is 'typ'.
'typ'+'ist'='TYPIST'
Can you help me to learn more?
(Other definitions for typist that I've seen before include "Worker taken from pool, perhaps" , "Someone paid to copy using a keyboard" , "Operator of a machine that prints one character at a time" , "Old secretary" , "Stenographer" .)
