'perpetually-seen' originates from the combination of 'perpetual,' which comes from Latin 'perpetuus,' meaning 'continuous,' and 'seen,' the past participle of 'see,' from Old English 'seon.'

'perpetual' evolved from Latin 'perpetuus' through Old French 'perpetuel' to Middle English 'perpetuel,' while 'seen' remained consistent from Old English 'seon.'

Initially, 'perpetual' meant 'continuous or everlasting,' and 'seen' meant 'observed.' Together, they convey the idea of something continuously observed.
