Some poinsettias displayed in a corner (5)
I believe the answer is:
inset
'a corner' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'some poinsettias displayed' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'INSET' can be found hidden inside 'poinsettias displayed'.
'in' is the link.
Can you help me to learn more?
(Other definitions for inset that I've seen before include "Small map within larger; teacher training day" , "Implant" , "It could be stuck between pages" , "Something put into something else" , "Small picture within borders of another" .)
