Hemingway’s twin personal assistants (4)
I believe the answer is:
papa
'hemingway's' is the definition.
(I've seen this in another clue)
'twin personal assistants' is the wordplay.
'twin' indicates the doubling of some letters.
'personal assistants' becomes 'pa' (this could be a standard abbreviation which I don't know about).
'pa' doubled is 'PAPA'.
Can you help me to learn more?
(Other definitions for papa that I've seen before include "one after Oscar" , "The old man" , "Mama's other half?" , "Dad" , "Father; letter P" .)
