A title of respect used when addressing or referring to royalty, such as a prince or princess (like 'Your Highness').
From Middle English 'highness,' combining 'high' with the suffix '-ness' (meaning 'quality or state of'), originally referring to royal dignity and elevated status.
Many European royal families still use different titles like 'Highness' and 'Majesty' based on strict rules—this tradition shows how language itself is used to maintain social hierarchy and respect for monarchy.
