Garden with lights on head? (9)
I believe the answer is:
landscape
'garden' is the definition.
(landscaping is a kind of gardening)
'lights on head?' is the wordplay.
'lights' becomes 'lands' (I can't justify this - if you can you should believe this answer much more).
'on' is a charade indicator (letters next to each other).
'head?' becomes 'cape' (both can mean a piece of land jutting over the sea).
'lands'+'cape'='LANDSCAPE'
'with' is the link.
Can you help me to learn more?
(Other definitions for landscape that I've seen before include "Artistic work" , "Piece of inland scenery" , "variety of shot" , "Possible prospect" , "(Painting of) scenery" .)
