Minor thoroughfare that is surrounded by strange trees (10)

I believe the answer is:

sidestreet

'minor thoroughfare' is the definition.
(I've seen this before)

'that is surrounded by strange trees' is the wordplay.
'that is' becomes 'idest' ('id est' can be a synonym of 'that is').
'surrounded by' means one lot of letters goes inside another.
'strange' indicates anagramming the letters.
'trees' is an anagram of 'sreet'.
'idest' put within 'sreet' is 'SIDESTREET'.

(Another definition for sidestreet that I've seen is " Minor thoroughfare".)

I've seen this clue in The Telegraph.
