Timid about games in the garden (9)
I believe the answer is:
shrubbery
'garden' is the definition.
(thesaurus)
'timid about games in' is the wordplay.
'timid' becomes 'shy' (similar in meaning).
'about games' becomes 'rubber' (I can't explain this - if you can you should believe this answer much more).
'in' is an insertion indicator.
'shy' enclosing 'rubber' is 'SHRUBBERY'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for shrubbery that I've seen before include "That might go in bed" , "Area where bushes are planted" , "collection of plants" , "Bushy part of garden" , "Bushy garden area" .)
