'invitee' originates from the verb 'invite,' which comes from Latin, specifically the word 'invitare,' where 'in-' meant 'toward' and 'vitare' meant 'to call or summon.'

'invite' changed from the Old French word 'inviter' and eventually became the modern English word 'invite.'

Initially, it meant 'to call or summon someone,' but over time it evolved into its current meaning of 'to request someone's presence at an event.'
