'take strength' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'us in stirring novel' is the wordplay.
'stirring' indicates anagramming the letters.
'novel' becomes 'new' (similar in meaning).
'us'+'in'='usin'
'usin' anagrammed gives 'unsi'.
'unsi'+'new'='UNSINEW'

'from' acts as a link.
