A Filipino word written with a final vowel may end phonetically in that vowel or in a glottal stop /ʔ/. The closure is not normally written in everyday text, but it can distinguish words: súka /ˈsu.ka/ means “vomit,” while sukà /ˈsu.kaʔ/ means “vinegar.”
Final /ʔ/ acts like a consonant closing the last syllable. It is not punctuation, a dramatic pause, or a special kind of stress. Stress and closure must be learned together because ordinary spellings such as suka, basa, and puno conceal both.
For articulation and word-initial or word-medial occurrences, begin with The Glottal Stop in Filipino. This page concentrates on the lexical contrast at word endings.
Four pronunciation patterns behind ordinary spelling
| Teaching form | Stress | Final /ʔ/ | Meaning |
|---|---|---|---|
| bása /ˈba.sa/ | Penultimate | No | reading; the root “read” |
| siyá /siˈja/ | Final | No | he, she, singular they |
| sukà /ˈsu.kaʔ/ | Penultimate | Yes | vinegar |
| basâ /baˈsaʔ/ | Final | Yes | wet |
The acute accent marks stress. A grave accent on the final vowel marks final glottal closure when stress falls earlier. A circumflex marks the combination of final stress and final closure. These are (academic/dictionary use). Ordinary prose normally writes basa, siya, suka, and basa without accents.
The dictionary stress and glottal-stop marks page shows how to decode these conventions across full entries.
How final closure feels
Sustain the final vowel briefly, then stop the airflow by closing the vocal folds. Do not close with the tongue as for /k/ or with the lips as for /p/. The word should end with a small catch in the throat. Compare open-ended súka with closed sukà.
Maasim ang sukà, kaya kaunti lang ang ilagay mo.
The vinegar is sour, so add only a little. (teaching mark) — sukà has penultimate stress and final /ʔ/.
May súka sa sahig, kaya linisin natin agad.
There is vomit on the floor, so let’s clean it immediately. (teaching mark) — súka has the same stress location but no final /ʔ/.
This is a controlled minimal pair: stress stays on the first syllable, and final closure alone changes the word. English speakers often hear only the shared vowels and consonants. Train the timing of the word ending, not merely the spelling.
Final stress does not predict final /ʔ/
Some final-stressed vowel-final words end openly, while others close. Siyá “he/she/they” has final stress without final /ʔ/; basâ “wet” has both.
Siyá ang kumausap sa doktor kaninang umaga.
They are the one who spoke with the doctor this morning. (teaching mark) — siyá ends in a stressed vowel without lexical final /ʔ/.
Basâ ang sapatos ko dahil sa malakas na ulan.
My shoes are wet because of the heavy rain. (teaching mark) — basâ ends in stressed /aʔ/.
Nor does a final glottal stop require final stress. Batà “child” and punò “tree/source” have earlier stress plus closure, while punô “full” has final stress plus closure.
Masayahing batà si Nico kahit mahaba ang biyahe.
Nico is a cheerful child even on a long trip. (teaching mark) — batà has penultimate stress and final /ʔ/.
Punô ang bus, kaya maghintay na lang tayo ng susunod.
The bus is full, so let’s just wait for the next one. (teaching mark) — punô has final stress and final /ʔ/.
The pair punò and punô shows a second possibility: both close glottally, but stress distinguishes “tree/source” from “full.” Final closure and stress are two intersecting contrasts, not one rule.
What happens before another word
Before a pause, final /ʔ/ is easiest to hear. Inside a phrase, speakers vary. In careful standard speech it can remain a distinct closure; in rapid Metro Manila speech (informal; regional: Metro Manila) it may weaken, with the preceding vowel's duration helping preserve the contrast. Many Southern Tagalog varieties (regional: Southern Tagalog) preserve phrase-medial closure more consistently.
Basâ ba ang bangko? — Hindi, tuyo na. Pinunasan ko kanina.
Is the bench wet? — No, it’s dry now. I wiped it earlier. (informal; teaching mark)
The /ʔ/ of basâ occurs before the question particle ba in careful pronunciation. A speaker may realize it less sharply in fast conversation, but that does not turn the lexical form into bása. Stress, vowel duration, closure, and context cooperate.
Hindi basâ ang damit; malamig lang dahil galing sa labas.
The clothes aren’t wet; they’re just cold from being outside. (neutral; teaching mark)
Negation does not remove the lexical closure. Hindi scopes over the adjective predicate, while basâ retains its pronunciation.
Linkers can change the surface ending
When a vowel-final root with /ʔ/ takes suffixal linker -ng, the linked surface form ends in /ŋ/, not in the sequence /ʔŋ/. Compare independent batà with batang masayahin, and independent basâ with basang damit.
Basang-basa ang manggas ng kamiseta ko.
The sleeve of my shirt is soaking wet. (neutral) — the linked form basang loses the word-final closure and ends in linker /ŋ/.
May matandang punong mangga sa likod ng bahay.
There is an old mango tree behind the house. (neutral) — the root is punò, but in linked punong mangga the linker supplies the surface /ŋ/.
Ordinary writing makes the alternation look simple—basa → basang, bata → batang, puno → punong—but the underlying words do not all have the same final pronunciation when used alone. Morphology can expose a different surface shape. Do not force the isolated /ʔ/ into a suffixed form.
Short connected context
May sukà pa ba? — Kaunti na lang. Punô pa ang isang bote, pero para iyon sa kusina.
Is there still vinegar? — Only a little. One bottle is still full, but that one is for the kitchen. (informal; teaching marks on sukà and punô)
The exchange contrasts grave-marked sukà with circumflex-marked punô. In normal messages, both marks disappear: May suka pa ba? Puno pa ang isang bote. Listeners recover the words from pronunciation and context.
Common Mistakes
1. Pronouncing vinegar without final closure. That produces súka, the word for vomit.
❌ May súka sa sawsawan.
Wrong for ‘There is vinegar in the dipping sauce’ — súka means vomit and lacks final /ʔ/.
✅ May sukà sa sawsawan.
There is vinegar in the dipping sauce. (penultimate stress plus final /ʔ/)
2. Dropping the closure from basâ. Stress alone is not a complete pronunciation.
❌ Basá ang sahig.
Incorrect for ‘The floor is wet’ — this has final stress but no final glottal stop.
✅ Basâ ang sahig.
The floor is wet. (final stress plus final /ʔ/)
3. Giving punô the stress pattern of punò. Both close with /ʔ/, so the stress contrast must remain.
❌ Punò ang baso.
Wrong for ‘The glass is full’ — punò has the pronunciation associated with ‘tree/source.’
✅ Punô ang baso.
The glass is full. (final stress plus final /ʔ/)
4. Preserving /ʔ/ mechanically before suffixal -ng. The linked surface form ends in /ŋ/.
❌ Basâ-ng damit ang nasa bag.
Incorrect — do not insert a pause, hyphen, or /ʔ/ before the linker.
✅ Basang damit ang nasa bag.
Wet clothes are in the bag. (linked form ending in /ŋ/)
Key Takeaways
- A written final vowel may be phonetically open or followed by lexical /ʔ/.
- Grave marks earlier stress plus final closure; circumflex marks final stress plus final closure.
- Stress and /ʔ/ contrast independently: súka/sukà differ by closure, while punò/punô differ by stress.
- Phrase-medial realization varies, but learners should acquire the careful lexical form.
- Before suffixal -ng, the surface form ends in /ŋ/ rather than preserving /ʔ/.
