Homes we rebuilt, note, in a particular location (9)
I believe the answer is:
somewhere
'location' is the definition.
(I know that somewhere is a type of location)
'homes we rebuilt note' is the wordplay.
'rebuilt' is an anagram indicator.
'note' becomes 're' (as in do-re-mi).
'homes'+'we'='homeswe'
'homeswe' with letters rearranged gives 'somewhe'.
'somewhe'+'re'='SOMEWHERE'
'in a particular' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for somewhere that I've seen before include "In an unspecified place" , "Bernstein classic" , "in unspecified location" , "location's vague" , "'. . . . . . . . . Over the Rainbow' (song)" .)
