Here are some other ways to say "you know" in Ilocano, depending on the context:
* "Kita mo" (kee-tah moh) - literally "You see it," implying you understand something.
* "Naawatan mo" (nah-wah-tah-wan moh) - meaning "You understand it."
* "Dimo?" (dee-moh) - This is a more informal way of saying "You know?" and can be used in place of "ammo mo" in casual conversation.
The best translation will depend on the specific situation and the level of formality you want to convey.
