kaya + Pronoun + Verb

In Filipino, expressing ability often involves the word kaya. While it can function as a noun meaning 'ability' (kakayahan), in this pattern, it acts as a modal-like word.

1. The Structure
The sentence follows this specific order:
Kaya + Genitive Actor + Linker + Verb (Infinitive).

2. The Actors (Genitive Case)
You must use the genitive case for the actor. Like the pseudo-verb gusto, kaya requires the actor to be in the genitive case:

• Pronouns: Use genitive case pronouns like ko, mo, or niya. Example: Kaya kong tumakbo. (I can run.)
• Personal Names: Use ni or nina. Example: Kaya ni Mariang magluto. (Maria can cook.)
• Common Nouns: Use ng or ng mga. Example: Kaya ng batang bumasa. (The child can read.)

3. The Linker Requirement
The linker is obligatory to connect the actor to the verb. The form changes based on the actor's ending:

• If the actor ends in a vowel (e.g., ko, niya, Maria), attach -ng: Kaya kong kumain.
• If the actor ends in a consonant (except n), use na: Kaya ng doktor na tumulong.
• If the actor ends in -n (e.g., namin, natin, Juan), a -g is added to form the -ng linker: Kaya ni Juang gawin ito.

4. Negation
To negate the ability, place hindi before kaya. When the actor is a pronoun, it acts as an enclitic and must move immediately after hindi. Because the pronoun moves, the linker shifts and attaches to kaya instead.
Example: Hindi ko kayang lumangoy. (I cannot swim.)
For non-pronoun actors (like names), the order remains the same: Hindi kaya ni Pedrong lumangoy. (Pedro cannot swim.)

5. Enclitic Placement
If an enclitic particle like ba or na is used, it follows standard Tagalog enclitic rules. Monosyllabic pronouns (like ko or mo) are first-order enclitics and always precede second-order particle enclitics like ba, na, or pa. The linker then attaches to the final enclitic.
Example: Kaya mo bang tapusin ito? (Can you finish this?) but Kaya ba nilang tapusin ito? (Can they finish this?)

6. Enclitic Pronoun Climbing
If the object of the verb is a pronoun (e.g., ako, siya), it climbs to the position immediately following kaya and its enclitics, and the linker attaches to this pronoun.
Example: Kaya mo ba akong tulungan? (Can you help me?)

7. Focus and Objects
Even though the actor is genitive, the object of the verb follows standard focus rules. If you use an object-focus verb, the object takes the ang case. Example: Kaya kong basahin ang libro. (I can read the book.) However, if you use an actor-focus verb, the object takes the ng case. Example: Kaya kong bumasa ng libro. (I can read a book.)

8. The 'Kita' Pronoun
When the actor is ko (I) and the object is ikaw or ka (you), Filipino uses the special portmanteau pronoun kita. The linker attaches to kita.
Example: Kaya kitang tulungan. (I can help you.)

9. Nuance vs. Other Modals
While puwede often means 'allowed' or 'possible,' kaya specifically means 'I have the strength, skill, or resources to do it.' If you say 'Kaya kong lumangoy,' you are saying you have the physical capacity or proficiency to swim.

10. Aspect and Time
As a pseudo-verb, kaya is aspectless. Time is established by context or time adverbs. To express aspect explicitly, you can switch to fully conjugatable verb forms of ability (e.g., kinaya, nakaya, makakaya).

11. Verbless Usage
If the action is already understood from context, the verb and the linker can be dropped entirely. For example, if someone asks if you can lift a heavy box, you can simply answer, Kaya ko. (I can manage it.) instead of Kaya kong buhatin.

12. Modal vs. Conjunction
Be careful not to confuse the modal kaya (ability) with the conjunction kaya (so / therefore). The modal takes a genitive actor and a linker (e.g., Kaya kong gawin - I can do it). The conjunction takes a nominative actor and no linker (e.g., Kaya ako umalis - That's why I left).
