In these sentences, we know that the focus is on the subject “ako” because the
object “tubig” is marked by ng.
These sentences respond to “who” questions:
Sino ang uminom ng tubig? Who drank the water?

Ako ang uminom ng tubig. (literally, I marker drank marker water.) OR
Uminom ako ng tubig. (literally, Drank I marker water.)

V. Studying the verbs “ umiinom drinking,” “kumakain eating,” and “bumibisita
visits”—object focus using the affix in

The most difficult part of grammar, however, is that the suffix changes
depending on the focus. When the focus in on the object, we use the affix in.
To form the completed verb, put in before the first vowel of the root word.

To form the incompleted verb, use the first two syllables of the completed
form and add the root word.

To form the contemplated verb, add the first syllable of the root word to the
root word and then add in. If the last letter of the word is a vowel, add h before
in.

Root Completed Incompleted Contemplated
inom ininom iniinom iinumin
kain kinain kinakain kakainin

bisita binisita binibisita bibisitahin

EXAMPLES : Tubig ang ininom ko.

Tubig ang iniinom ko.
Tubig ang iinumin ko.

In these sentences, we know that the focus is on the object because of the
marker ang.

These sentences respond to “what” questions:
Ano ang ininom mo?

What did you drink?
