Streaked on the street, naked (8)
I believe the answer is:
stripped
'naked' is the definition.
(stripped of clothing)
'streaked on the street' is the wordplay.
'streaked' becomes 'ripped' (I am not sure about this - if you are sure you should believe this answer much more).
'on' means one lot of letters go next to another.
'the street' becomes 'st' (abbreviation).
'ripped' put after 'st' is 'STRIPPED'.
Can you help me to learn more?
(Other definitions for stripped that I've seen before include "Pets drip (anag)" , "having no gear" , "Undressed" , "behaved 'naughtily' in club?" , "Removed paint - or clothes" .)
