Flowers, trees etc. aren't cultivated round university (6)
I believe the answer is:
nature
'flowers trees etc' is the definition.
I can't tell whether this defines the answer.
'aren't cultivated round university' is the wordplay.
'cultivated' indicates anagramming the letters.
'round' is an insertion indicator.
'university' becomes 'U' (abbreviation for university).
'arent' is an anagram of 'natre'.
'natre' going around 'u' is 'NATURE'.
Can you help me to learn more?
(Other definitions for nature that I've seen before include "All non-artificial phenomena" , "World of plants, animals, landscapes etc" , "Inborn characteristics" , "what's seen in the country?" , "scientific journal" .)
