Literary world to stroke good person in welcome (4,6)
I believe the answer is:
grub street
'literary world' is the definition.
(term for the world of authors and journalists)
'stroke good person in welcome' is the wordplay.
'stroke' becomes 'rub' (I've seen this in another clue).
'good person' becomes 'st' (saint).
'in' means one lot of letters goes inside another.
'welcome' becomes 'greet' (I've seen this before).
'rub'+'st'='rubst'
'rubst' going inside 'greet' is 'GRUB STREET'.
'to' is the link.
(Other definitions for grub street that I've seen before include "Place for shabby writers" , "Former home of hack writers" , "The world of poor journalists and writers" .)
