Notes on Different Meanings

• The word "hoặc" functions almost exclusively as a conjunction. The verbal meaning ("làm cho lầm lẫn" - to cause confusion) listed in some historical or comprehensive dictionaries is archaic and extremely rare in modern Vietnamese. For contemporary learners, "hoặc" should be understood and used solely as a conjunction meaning "or".
