It contains fruit or vegetable (7)
I believe the answer is:
orchard
'it contains fruit' is the definition.
The definition suggests a singular noun which matches the answer. I also know that 'fruit' relates to this answer.
'or vegetable' is the wordplay.
'vegetable' becomes 'chard' (chard is a kind of vegetable).
'or'+'chard'='ORCHARD'
Can you help me to learn more?
(Other definitions for orchard that I've seen before include "Field of fruit trees" , "Garden of fruit trees" , "Location of fruit" , "where fruit trees grow" , "Enclosure containing fruit trees" .)
