Tyrannosaurus is around unfortunately (8)
I believe the answer is:
dinosaur
'tyrannosaurus' is the definition.
The answer and definition can be both animals as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'is around unfortunately' is the wordplay.
'unfortunately' indicates anagramming the letters.
'is'+'around'='isaround'
'isaround' with letters rearranged gives 'DINOSAUR'.
Can you help me to learn more?
(Other definitions for dinosaur that I've seen before include "One as T. Rex, triceratops" , "Creature no longer" , "Prehistoric reptile" , "type unable to adapt" , "Extinct reptilian animal" .)
