ang tatay mo
= ang iyong tatay
ang lapis mo
= ang iyong lapis
This Tagalog pronoun mo is used only when the ‘you’ is one person. If more than one person, use ninyo (n’yo).
Sometimes mo can simply be translated as ‘you’ when paired with the word ang.
Ang payat mo!
You are so thin!
Ang bagal mo!
You are so slow!
Other uses for mo are harder to translate.
The mo here refers to asking you to eat something.
There is no need to translate ‘it’ into Tagalog because of the way the verb is conjugated.
