Fearful lizard very upsetting in roads taking a bend (8)
I believe the answer is:
dinosaur
'fearful lizard' is the definition.
'dinosaur' can be an answer for 'lizard' (thesaurus). I'm not sure about the 'fearful' bit.
'upsetting in roads taking a bend' is the wordplay.
'upsetting' is an anagram indicator.
'taking' is an insertion indicator.
'a bend' becomes 'U' (a U-bend is a kind of bend - pipe under sink).
'in'+'roads'='inroads'
'inroads' is an anagram of 'dinosar'.
'dinosar' going around 'u' is 'DINOSAUR'.
'very' is the link.
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dinosaur that I've seen before include "I adorn US with this old creature" , "Prehistoric monster found on Darius" , "Out of date person or thing" , "Settle under canvas" , "One as T. Rex, triceratops" .)
