Having value beyond monetary measure; extremely valuable or precious; also used humorously to mean amusing.
From 'price' (Old French 'pris') plus suffix '-less' meaning without. Paradoxically means both 'without price because worthless' and 'without price because too valuable', with context determining meaning.
The word 'priceless' creates a fascinating paradox - technically meaning 'without price,' it has evolved to mean 'invaluable.' This semantic shift shows how language can flip meaning entirely while keeping the same form.
