Shortened Forms of Questions
Contracting words in an interrogative sentence is also a noticeable speaking habit in Filipino. If you remember the lessons on ligatures and pronouns, you'll see that rules about shortened forms also apply in interrogative sentences.
Recall the rules about shortened forms of pronouns.
- "" becomes "'to"
- "" becomes "'yan"%%%
- "" becomes "'yon"
Also, try to recall rules about word connectives/ligatures.
- use of suffix ligature "-ng" and "-g" to connect the word ligature "na" to the modifier
In the following example, you will see how the interrogative sentences are shortened by connecting the article "ang" to the Filipino question words "anó," "sino," and "kanino". To further shorten the interrogative sentences, the subject is dropped, but is still represented by the pronouns and a particular action that points to it. Notice that the suffix is also dropped from the question word.
Anó
Examples:
What is that building?
ang ng ? 
What is that building?
Anóng gusali 'yón?
What is that? (pointing at the building)
Anó 'yon?
Sino
Examples:
Who is that celebrity?
ang ng ?
Who is that celebrity?
Sinong artista 'yon?
Who is that? (pointing at the celebrity)
Sino 'yon?
Kanino
Examples:
Whose wristwatch is this?
ang ng ?
Whose wristwatch is this?
Kaninong reló 'to?
Whose is this? (holding the wristwatch)
Kanino 'to?
