'charge?' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'training one side i' is the wordplay.
'training' is an anagram indicator (to train can mean to grow something into a shape).
'one'+'side'+'i'='onesidei'
'onesidei' with letters rearranged gives 'DEIONISE'.

'take' is the link.
