kasi
Because / You See
Kasi is the most common way to say "because" in casual Filipino. It can start a clause or act as a "floating" particle that follows the first word of a sentence to add an explanatory tone ("you see").
How It Works
1. The Explanatory Particle
In daily speech, kasi often appears right after the first word of a sentence. This gives the sentence a "you see" or "it's because..." nuance.
Example: Mainit kasi. (It's because it's hot / It's hot, you see.)
2. Word Order and Enclitics
As an enclitic particle, kasi follows specific placement rules. If a sentence starts with a short pronoun like ka or ko, kasi must come after the pronoun.
Example: Wala ka kasi kahapon. (Because you weren't here yesterday.)
3. The "Blame" Construction
When used with a person's name or a pronoun in a short exclamation, kasi points to them as the cause of a problem (similar to "It's your fault!").
Example: Ikaw kasi! (It's because of you! / Look what you did!)
4. Register and Style
Kasi is strictly informal. In formal writing or speeches, you should use dahil or the even more formal sapagkat. Unlike dahil, kasi cannot be followed by the marker sa (e.g., you cannot say "kasi sa iyo").
Examples (5)
- Late ako kasi nasiraan ng bus.
I'm late because the bus broke down.
Word by Word: Late I because broke-down [marker] bus.
Here, 'kasi' acts as a conjunction linking the result (being late) to the cause (bus breakdown).
- Umuulan kasi, kaya hindi kami lumabas.
It's raining, you see, so we didn't go out.
Word by Word: Raining because, so not we went-out.
In this sentence, 'kasi' is an enclitic particle providing context for the following action.
- Masaya ako kasi nandito ka.
I'm happy because you are here.
Word by Word: Happy I because here you.
A common way to express a positive reason in casual conversation.
- Ayan kasi, hindi ka nakinig sa akin.
There you go, because you didn't listen to me.
Word by Word: There-it-is because, not you listened to me.
This uses 'kasi' to imply blame or a 'told-you-so' sentiment regarding a negative outcome.
- Gusto ko kasi ng kape.
It's because I want some coffee.
Word by Word: Want I because [marker] coffee.
Notice how 'kasi' follows the short pronoun 'ko'. This is the natural enclitic position.
Common Mistakes
Placing 'kasi' before a short pronoun.
Gusto kasi ko ng tubig.Gusto ko kasi ng tubig.Short pronouns like 'ko', 'mo', and 'ka' always take priority in the sentence order. 'Kasi' must follow them.
Using 'kasi sa' to mean 'because of'.
Hindi ako nakapunta kasi sa ulan.Hindi ako nakapunta dahil sa ulan.Unlike 'dahil', 'kasi' cannot be paired with 'sa' to create a prepositional phrase. Use 'dahil sa' for 'because of [noun]'.
Using 'kasi' in very formal academic writing.
Ang ekonomiya ay bumagsak kasi...Ang ekonomiya ay bumagsak dahil...'Kasi' is very casual. In formal contexts, 'dahil' or 'sapagkat' is preferred to maintain a professional tone.
How It Connects
Learn This First
To use 'kasi' correctly, you need to understand how Filipino sentences are structured (predicate-first) and how certain short words, called enclitics, jump to the second position in a sentence. It also helps to know the formal word for 'because' (dahil) to understand when to use the more informal 'kasi' instead.
