'dynamically-managed' originates from the combination of 'dynamic' and 'manage.' 'Dynamic' comes from the Greek word 'dunamikos,' meaning 'powerful,' and 'manage' comes from the Italian 'maneggiare,' meaning 'to handle.'

'Dynamic' evolved from the Greek 'dunamikos' to the Latin 'dynamica,' and eventually became the modern English word 'dynamic.' 'Manage' evolved from the Italian 'maneggiare' to the French 'maneger,' and eventually became the modern English word 'manage.'

Initially, 'dynamic' meant 'powerful' or 'forceful,' but over time it evolved to mean 'characterized by constant change or activity.' 'Manage' initially meant 'to handle or control,' and this meaning has largely remained the same in modern usage.
