### Clue: Grade a row with no end of stew in traffic this? (4,4)
### Answer: ROAD RAGE 
 ### Explanation: Definition: stew in traffic this
 **Anagram of**
(… stew) [GRADE A + "row" **minus its last letter**(with no end) ]. It seems as if "stew" is doubling up: in the defn. to indicate agitation, and as an anagram indicator. And perhaps also to indicate the missing "w" ("end of stew"). Take your pick.
