Regard first pair of boots as garden feature (6)
I believe the answer is:
gazebo
'garden feature' is the definition.
(I've seen this in another clue)
'regard first pair of boots' is the wordplay.
'regard' becomes 'gaze' (synonyms).
'first' means one lot of letters go next to another.
'pair of boots' becomes 'bo' (I can't explain this - if you can you should believe this answer much more).
'gaze'+'bo'='GAZEBO'
'as' is the link.
Can you help me to learn more?
(Other definitions for gazebo that I've seen before include "Garden viewpoint" , "garden feature" , "Small garden building for shade and rest" , "outhouse" , "Small summerhouse for shade" .)
