FYI: The word "yo" just like the other Haitian Creole pronouns can be confusing.
"Yo" is the plural definite article → as in: liv yo - the books
"yo" is the subject pronoun → as in: Yo pale - they talk
"yo" is the object pronoun → as in: Mwen renmen yo - I love them
"yo" is the possessive adjective → as in: Sa se kay yo. - This is their house.
