Quite slowly, run through poor part of Los Angeles? (9)
I believe the answer is:
larghetto
'of los angeles?' is the definition.
I can't tell whether this definition defines the answer.
'quite slowly run through poor part' is the wordplay.
I cannot really see how this works, but
'run' could be 'r' (cricket abbreviation) and 'r' is present in the answer.
'part' could be 'la' (la is a kind of part) and 'la' is located in the answer.
The remaining letters 'ghetto' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for larghetto that I've seen before include "movement" , "Rather slow" , "rather slowly" , "Slowish" , "Somewhat slow (music)" .)
