In courtyard, dislike new display (12)
I believe the answer is:
presentation
'display' is the definition.
(presentation is a kind of display)
'in courtyard dislike new' is the wordplay.
'in' means one lot of letters goes inside another.
'courtyard' becomes 'patio' (I've seen this before).
'dislike' becomes 'resent' (resenting is a kind of disliking**).
'new' becomes 'n'.
'patio' going around 'resent' is 'presentatio'.
'presentatio'+'n'='PRESENTATION'
(Other definitions for presentation that I've seen before include "Formal act of giving" , "show" , "Formal introduction" , "Display" , "Illustrated formal talk" .)
