'consistently-seen' originates from the combination of 'consistent' and 'seen', where 'consistent' means 'acting or done in the same way over time' and 'seen' is the past participle of 'see', meaning 'to perceive with the eyes'.

'consistently-seen' combines the adjective 'consistent' with the past participle 'seen' to form a compound adjective.

Initially, 'consistent' meant 'standing firm' and 'seen' meant 'perceived', but together they evolved to describe something regularly observed.
