Son with scam: teen regularly affected (8)
I believe the answer is:
stricken
'affected' is the definition.
(similar in meaning)
'son with scam teen regularly' is the wordplay.
'son' becomes 's' (genealogical abbreviation for son).
'with' is a charade indicator (letters next to each other).
'scam' becomes 'trick' (I can't justify this - if you can you should give a lot more credence to this answer).
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
The alternating letters of 'teen' are 'en'.
's'+'trick'+'en'='STRICKEN'
Can you help me to learn more?
(Other definitions for stricken that I've seen before include "Risk cent, being affected as by grief" , "Word that can be appended to both 1 and 2 down" , "Severely afflicted" , "Hit" , "Wounded" .)
