Kids involved in a sordid row (4)
I believe the answer is:
skid
'a sordid row' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe there's a link between them I don't understand?
'kids involved' is the wordplay.
'involved' indicates anagramming the letters (involved can mean confusing or complex).
'kids' anagrammed gives 'SKID'.
'in' is the link.
Can you help me to learn more?
(Other definitions for skid that I've seen before include "Slide uncontrollably" , "Runner" , "Slip out of control" , "Slide at an angle" , "Uncontrolled slide" .)
