'absurd' is the definition.
Both the answer and definition are adjectives. Maybe there's an association between them I don't understand?

'negative poles seen to change?' is the wordplay.
'negative' becomes 'no' (no is a kind of negative).
'poles' becomes 'ns' (North and South poles).
'to change?' indicates an anagram (I've seen 'to change' mean this).
'seen' with letters rearranged gives 'ense'.
'no'+'ns'+'ense'='NONSENSE'

Can you help me to learn more?
