Native Filipino cardinal numbers are the most versatile number system in contemporary Filipino. They count people and objects, measure time and distance, state quantities, and work in both conversation and formal writing. Spanish-derived and English numbers coexist with them, but those borrowed systems have stronger domain and register preferences.
The central grammatical fact is the linker: before a counted noun, isa, dalawa, tatlo, lima, pito, walo, and sampu take attached -ng, while consonant-final numbers such as apat and anim take separate na. A bare number can instead stand as a predicate or answer when the counted noun is already understood.
One to ten
| Digit | Counting form | Before a noun | Example phrase |
|---|---|---|---|
| 1 | isa | isang | isang tiket |
| 2 | dalawa | dalawang | dalawang tiket |
| 3 | tatlo | tatlong | tatlong tiket |
| 4 | apat | apat na | apat na tiket |
| 5 | lima | limang | limang tiket |
| 6 | anim | anim na | anim na tiket |
| 7 | pito | pitong | pitong tiket |
| 8 | walo | walong | walong tiket |
| 9 | siyam | siyam na | siyam na tiket |
| 10 | sampu | sampung | sampung tiket |
The table shows ordinary neutral forms. Sero “zero” is historically borrowed rather than part of the inherited one-to-ten series, but it is fully established in Filipino and is used in mathematics, scores, codes, and measurements.
Dalawang tiket ang binili ko para sa konsiyerto.
I bought two tickets for the concert. (neutral)
Anim na upuan ang bakante sa likod.
Six seats at the back are vacant. (neutral)
The attached -ng in dalawang and separate na after anim perform the same linking function. The form depends only on the end of the numeral expression.
Numbers can stand without a noun
A bare cardinal can answer Ilan? “How many?” or head a quantity predicate. No linker is needed when no following noun is being connected.
Ilan ang darating mamayang gabi? — Walo, kasama ang dalawang bata.
How many will arrive tonight? — Eight, including the two children. (neutral conversation)
Tatlo ang bakanteng mesa, pero isa lang ang malapit sa bintana.
Three tables are vacant, but only one is near the window. (neutral)
In Tatlo ang bakanteng mesa, tatlo is the predicate quantity. In tatlong bakanteng mesa, it would be a modifier inside a noun phrase. English uses three unchanged in both environments; Filipino makes the phrase boundary audible through the linker.
Eleven through ninety-nine
The teens and tens have established surface forms that must be learned. Sound assimilation makes them more than transparent strings of smaller words.
| Range | Forms | Pattern |
|---|---|---|
| 11–19 | labing-isa, labindalawa, labintatlo, labing-apat, labinlima, labing-anim, labimpito, labingwalo, labinsiyam | established labing-/labin-/labim- forms |
| 20–90 | dalawampu, tatlumpu, apatnapu, limampu, animnapu, pitumpu, walumpu, siyamnapu | multiples of ten with assimilated linking |
| 21, 32, etc. | dalawampu't isa, tatlumpu't dalawa | multiple of ten + contracted at + unit |
Hyphens in labing-isa and labing-apat preserve the boundary before a vowel-initial unit. The apostrophe in dalawampu't isa represents contracted at “and”; it is not a stress mark.
Dalawampu't limang kalahok ang nakapagparehistro bago magtanghali.
Twenty-five participants registered before noon. (neutral)
The complete number dalawampu't lima ends in a vowel, so it takes attached -ng before kalahok: dalawampu't limang kalahok.
For larger exact quantities, contemporary Filipino uses daan “hundred,” libo “thousand,” and milyon “million”: isang daan, dalawang daan, isang libo, tatlong milyon. Long spelled-out numbers are possible but digits are often clearer in administrative and technical writing.
May isang daan at dalawampung aklat sa bagong estante.
There are one hundred twenty books on the new shelf. (neutral)
Here the whole quantity ends in dalawampu, which takes -ng before aklat. Do not attach a linker to every internal number component; the final number expression links to the counted noun.
Measurement uses the same linker
Native numerals combine naturally with units of time, length, weight, and volume.
Naghintay kami nang apat na oras bago dumating ang mekaniko.
We waited for four hours before the mechanic arrived. (neutral)
Kailangan natin ng tatlong kilo ng bigas para sa handaan.
We need three kilos of rice for the celebration. (neutral)
In apat na oras, na links the number to the unit. The preceding nang marks duration as an adverbial measurement. In tatlong kilo ng bigas, attached -ng links number to unit, while separate ng introduces the measured contents. The measure-phrase guide develops this layered structure.
Exact quantity versus approximation
An exact numeral normally makes ordinary plural mga unnecessary: tatlong kahon is exactly three boxes. When mga immediately precedes a number, it commonly means “about/approximately.”
Mga sampung minuto lang ang lakad mula rito.
It is only about a ten-minute walk from here. (neutral approximation)
This use is not an error or redundant plural marking. Compare exact sampung minuto with approximate mga sampung minuto. The plural-marker page explains why mga changes function before a numeral.
Choosing among three number traditions
Dalawang oras ang biyahe, pero alas-dos ang alis ng bus.
The trip takes two hours, but the bus leaves at two o'clock. (neutral)
This controlled contrast uses native dalawang oras for duration and Spanish-derived alas-dos for clock time. English numbers are also frequent in codes, classroom labels, technology, and code-switched conversation. The systems coexist, but speakers choose by domain rather than translating every numeral in isolation.
Native forms remain the broadest neutral choice for counting and measurement. Spanish-derived forms are strongly established for clock time and prices; English forms are especially frequent in technical, educational, and (code-switched) settings. Dedicated pages cover both borrowed traditions.
Common Mistakes
1. Omitting the linker before a noun
❌ Kailangan ko ng dalawa kopya ng resibo.
Incorrect — dalawa needs attached -ng before kopya.
✅ Kailangan ko ng dalawang kopya ng resibo.
I need two copies of the receipt. (neutral)
2. Attaching -ng after a consonant other than n
❌ Apatng plato ang ilalagay sa mesa.
Incorrect — apat ends in t, so the linker is separate na.
✅ Apat na plato ang ilalagay sa mesa.
Four plates will be placed on the table. (neutral)
3. Adding mga when an exact count is intended
❌ Mga limang aplikante ang dumating.
Wrong for exactly five applicants — mga before a numeral makes the quantity approximate.
✅ Limang aplikante ang dumating.
Five applicants arrived. (neutral exact count)
The first sentence is grammatical if the speaker means “about five.” The correction changes precision, not merely form.
4. Mixing native-number and Spanish currency grammar
❌ Nagbayad ako ng dalawang pesos sa supot.
Nonstandard mixed system — native dalawang combines with Filipino singular currency unit piso.
✅ Nagbayad ako ng dalawang piso sa supot.
I paid two pesos for the bag. (neutral native-number pattern)
Spanish-derived dos pesos is also established in price contexts, but it is a different complete pattern.
Key Takeaways
- Native Filipino cardinals are the most versatile forms for exact counting and measurement.
- Before a noun, add -ng after a vowel, -g after n, and separate na after another consonant.
- Bare numbers can answer ilan or head quantity predicates without a linker.
- Learn the actual assimilated teen and tens forms; do not invent them from arithmetic alone.
- Mga + number means approximation, and borrowed number systems have their own domain and register conventions.
