Publisher presses writer to show feelings (4,2)
I believe the answer is:
open up
'show feelings' is the definition.
'open up' can be an answer for 'show' (thesaurus). I am unsure of the 'feelings' bit.
'publisher presses writer' is the wordplay.
'publisher' becomes 'OUP' (abbreviation for Oxford University Press).
'presses' indicates putting letters inside (some letters are pressed between others).
'writer' becomes 'pen' (something which writes).
'oup' placed around 'pen' is 'OPEN UP'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for open up that I've seen before include "Speak freely and without restraint" , "launch" , "Demand for admittance - become frank" , "become less cloistered" , "Let police in - share feelings" .)
