Japanese plant university introduced to a Caribbean island (6)
I believe the answer is:
aucuba
'japanese plant' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'university introduced to a caribbean island' is the wordplay.
'university' becomes 'U' (abbreviation for university).
'introduced to' means one lot of letters goes inside another.
'caribbean island' becomes 'cuba' (I've seen this in another clue).
'a'+'cuba'='acuba'
'u' put inside 'acuba' is 'AUCUBA'.
Can you help me to learn more?
(Other definitions for aucuba that I've seen before include "Laurel" , "shrub" .)
