Are prancing into the arena and standing on their hind legs (7)
I believe the answer is:
rearing
'standing on their hind legs' is the definition.
I can't tell whether this defines the answer.
'are prancing into the arena' is the wordplay.
'prancing' indicates an anagram.
'into' is an insertion indicator.
'the arena' becomes 'ring' (eg a boxing ring).
'are' anagrammed gives 'ear'.
'ear' placed into 'ring' is 'REARING'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for rearing that I've seen before include "Caring for and educating" , "Bringing up" , "Setting up" .)
