(mo)

1. Possessive Pronoun ("your"):
   - Example: _Ana libro mo._ ("Your book.")
   - Indicates ownership or possession, referring to something belonging to the person being addressed.

2. Ergative Marker (Actor Marker in Actor-Focus constructions):
   - Example: Kaenen mo.  ("You eat it..")
   - Marks the agent (doer) of the action in imperative or certain verb constructions, often used with actor-focus verbs.

In short, *mo* indicates either possession ("your") or identifies the doer of an action in specific grammatical constructions.
