'it didn't grow at tyburn' is the definition.
The definition suggests a singular noun which matches the answer.

'it didn't' is the wordplay.
'it' becomes ''t' (abbreviation. e.g. in 'tis).
'didn't' becomes 'ree' (I can't justify this - if you can you should believe this answer much more).
't'+'ree'='TREE'

Can you help me to learn more?
