'easily split' is the definition.
Both the answer and definition are adjectives. Maybe there's a link between them I don't understand?

'broken if large' is the wordplay.
'broken' indicates an anagram.
'if'+'large'='iflarge'
'iflarge' with letters rearranged gives 'FRAGILE'.

'or' is the link.

Can you help me to learn more?
