Toiler you picture inputting something thunderously, primarily? (6)
I believe the answer is:
typist
'toiler you picture inputting something thunderously primarily?' is the definition.
I can't judge whether this defines the answer.
'toiler you picture inputting something thunderously primarily?' is the wordplay.
'primarily?' suggests taking the first letters (I've seen 'primarily' mean this).
The initial letters of 'toiler you picture inputting something thunderously' is 'TYPIST'.
Can you help me to learn more?
(Other definitions for typist that I've seen before include "Keyboard user" , "One uses an old-fashioned keyboard" , "The old-style secretary, for one" , "Keyboard operator" , "Old secretary" .)
