'properly' originates from Latin, specifically the word 'proprius,' meaning 'one's own.' 'State' comes from Latin 'stare,' meaning 'to stand.'

'proprius' transformed into the Old French 'propre,' and eventually became the modern English word 'properly.' 'Stare' evolved into the Old French 'stat,' leading to the modern English 'state.'

Initially, 'properly' meant 'in a manner belonging to oneself,' but evolved to mean 'correctly.' 'State' originally meant 'to stand,' but now means 'to express in words.'
