'spontaneously-created' originates from Latin, specifically the word 'spontaneus,' where 'sponte' meant 'of one's own accord,' and 'create' from Latin 'creare,' meaning 'to bring forth.'

'spontaneus' transformed into the English word 'spontaneous,' and 'creare' became 'create,' eventually forming the compound adjective 'spontaneously-created.'

Initially, 'spontaneous' meant 'of one's own accord,' and 'create' meant 'to bring forth.' The compound adjective now refers to something formed without premeditation.
