It has to be borne (5)
I believe the answer is:
fruit
'it has to be borne' is the definition.
The definition suggests a singular noun which matches the answer.
This is the entire clue.
Can you help me to learn more?
(Other definitions for fruit that I've seen before include "See 9" , "Greengrocer's produce" , "Kiwi, mandarin etc" , "Eg, banana or apple" , "Result of work/activity" .)
