Where typist can access letters in crucial committee (8)
I believe the answer is:
keyboard
'where typist can access letters' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'crucial committee' is the wordplay.
'crucial' becomes 'key' (I've seen this in another clue).
'committee' becomes 'board' (board is a kind of committee).
'key'+'board'='KEYBOARD'
'in' is the link.
Can you help me to learn more?
(Other definitions for keyboard that I've seen before include "There are various characters on this" , "Part of piano. computer, etc" , "Computer input device" , "It can produce notes" , "one lays hands on" .)
