Passages in street on dry island (7)
I believe the answer is:
stretti
'passages' is the definition.
(I've seen this before)
'street on dry island' is the wordplay.
'street' becomes 'st'.
'on' becomes 're' ('on' can be mean 'with reference to'**).
'dry' becomes 'tt' (abbreviation for teetotal).
'island' becomes 'i'.
'st'+'re'+'tt'+'i'='STRETTI'
'in' acts as a link.
(Other definitions for stretti that I've seen before include "musical pieces" , "Pieces of music" , "Musical passages" , "fugal devices" .)
