'vigorously-produced' originates from the combination of 'vigorously' and 'produced'. 'Vigorously' comes from the Latin word 'vigor', meaning 'liveliness or energy', and 'produced' is derived from the Latin 'producere', meaning 'to bring forth'.

'Vigorously' evolved from the Latin 'vigor' through Old French 'vigueur', while 'produced' transformed from Latin 'producere' through Old French 'produire'.

Initially, 'vigorously' meant 'with liveliness', and 'produced' meant 'brought forth'. Together, they convey the idea of something created with energy.
