It grows in the street (4)
'it grows' is the definition.
'in the street' is the wordplay.
'in' says the answer is hidden in the clue.
'TREE' is hidden within 'street'.
(Other definitions for tree that I've seen before include "Genealogist's graphic" , "Plant with bark" , "Chestnut or elm?" , "Plane or pine, for example?" , "Big plant" .)
'in the street' is the definition.
I can't tell whether this definition defines the answer.
'it grows' is the wordplay.
'it' becomes ''t' (abbreviation. e.g. in 'tis).
'grows' becomes 'ori' (I can't explain this - if you can you should give a lot more credence to this answer).
't'+'ori'='TORI'
Can you help me to learn more?
(Other definitions for tori that I've seen before include "rings" , "Large mouldings on columns" , "doughnuts" .)
