Trashy American town regularly passing notice (3-3)
I believe the answer is:
two-bit
'trashy american' is the definition.
The definition suggests an adjective which matches the answer.
'town regularly passing notice' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'passing notice' becomes 'obit' (I've seen this in another clue).
The alternating letters of 'town' are 'tw'.
'tw'+'obit'='TWO-BIT'
Can you help me to learn more?
(Other definitions for two-bit that I've seen before include "Paltry" , "Cheap (US colloq.)" , "Cheap, worthless (US)" , "Inferior - cheap" , "Cheap - insignificant" .)
