Traveller must respect this awfully simple diet (5,5)
I believe the answer is:
speed limit
'traveller must respect this' is the definition.
The definition suggests a singular noun which matches the answer.
'awfully simple diet' is the wordplay.
'awfully' indicates anagramming the letters.
'simple'+'diet'='simplediet'
'simplediet' anagrammed gives 'SPEED-LIMIT'.
Can you help me to learn more?
(Other definitions for speed limit that I've seen before include "maximum rate by law" , "rate cap" , "Flashily ignoring this may gain you points" , "it restricts one's career" , "Rule facing drivers" .)
