Fearful lizard very upsetting in roads taking a bend (8)
I believe the answer is:
dinosaur
'fearful lizard very' is the definition.
I can't judge whether this definition defines the answer.
'upsetting in roads taking a bend' is the wordplay.
'upsetting' indicates an anagram.
'taking' indicates putting letters inside.
'a bend' becomes 'U' (a U-bend is a kind of bend - pipe under sink).
'in'+'roads'='inroads'
'inroads' anagrammed gives 'dinosar'.
'dinosar' placed around 'u' is 'DINOSAUR'.
Can you help me to learn more?
(Other definitions for dinosaur that I've seen before include "I adorn US with this old creature" , "Prehistoric monster found on Darius" , "Out of date person or thing" , "Settle under canvas" , "One as T. Rex, triceratops" .)
