Adverbial clauses of time locate one situation relative to another: Nang dumating ang doktor, naghihintay na ang pasyente “When the doctor arrived, the patient was already waiting.” Filipino chooses connectors according to whether the time is a specific past occasion, an expected or repeated occasion, an overlap, a boundary, or an interval beginning or ending with an event.
Verb morphology still expresses aspect rather than English tense. The connector establishes the temporal relation, while completed, incompleted, and contemplated forms present how each event unfolds.
For the interaction between aspect and embedding beyond temporal clauses, see aspect in subordinate clauses.
Core temporal connectors
| Connector | Core relation | Typical use/register |
|---|---|---|
| nang | when, at the time that | specific past event; neutral-careful |
| kapag | when/whenever | habitual, expected, or future occasion |
| pag | when/once | short form, informal |
| habang | while | temporal overlap |
| bago | before | earlier than a reference event |
| pagkatapos / matapos | after | later than a completed boundary |
| mula nang | since | starting boundary continuing to reference time |
| hanggang / hanggang sa | until | ending boundary |
Specific past time with nang
Start with an independent completed clause:
Nagsara na ang botika.
The pharmacy has already closed. (independent clause)
Completed nagsara directly presents the closing as realized. When the same event becomes a temporal frame after nang, a mag- verb commonly appears in its basic dependent form:
Dumating ang doktor nang magsara na ang botika.
The doctor arrived when the pharmacy had already closed. (independent event plus temporal clause)
Completed dumating presents the arrival as realized. Basic magsara does not independently carry the completed nag- marking of nagsara; temporal nang, na, and the completed main event together yield the bounded past interpretation. Temporal nang is distinct from nominal marker ng and from manner nang.
The temporal clause may come first:
Nang magsara na ang botika, tumawag ang nars sa ibang sangay.
When the pharmacy had already closed, the nurse called another branch.
The independent/embedded pair shows that embedding can alter the form of a mag- predicate without turning aspect into English tense. Moving the temporal clause initially changes information structure, not the underlying temporal relation: initial placement makes the closing a frame for the call, while final placement adds it as a reference point after the main event.
Noong commonly introduces a past time noun phrase—noong Lunes, noong bata pa ako—and many contemporary speakers also use it with clause-like material. For a discrete event predicate in careful prose, nang dumating, nang magsara, and similar forms remain dependable.
Expected and repeated occasions with kapag
Kapag umuulan nang malakas, bumabaha ang kalsada sa tapat ng paaralan.
Whenever it rains heavily, the road in front of the school floods.
Incompleted forms support a habitual relation. Manner nang malakas modifies umuulan and is not the temporal connector.
Kapag dumating na ang mga resulta bukas, tatawagan kita agad.
When the results arrive tomorrow, I will call you immediately.
The event is expected but not yet realized. Filipino uses contemplated tatawagan in the main clause; it does not use an English present-tense rule after when.
Short pag for kapag is ordinary in conversation (informal). In careful standard spelling and more formal prose, kapag umuwi ka or pag-uwi mo may be preferable depending on whether the structure is a clause or a nominalized event:
Pag-uwi mo, padalhan mo ako ng mensahe.
When you get home, send me a message. (informal-neutral)
The hyphenated pag-uwi is a nominalized time expression, not simply shortened kapag followed by a spaced verb. The two colloquial patterns overlap in speech but differ orthographically.
Overlap with habang
Habang naghihintay kami sa laboratoryo, sinusuri ng doktor ang mga resulta.
While we are waiting at the laboratory, the doctor is examining the results.
Both incompleted predicates present overlapping activity. Exclusive kami means the addressee is not part of the waiting group.
Huwag kang tumawid habang pula pa ang ilaw.
Do not cross while the light is still red.
Huwag forms a negative command; habang supplies the interval during which the prohibition holds. English while can also mean “although/whereas,” but Filipino often uses samantalang, pero, or a clearer contrast construction when temporal overlap is not intended.
Before and after
Bago umalis si Nilo, pinatay niya ang lahat ng ilaw.
Before Nilo left, he turned off all the lights.
The actor is overt in both clauses, preventing uncertainty about who left and who turned off the lights. When subjects are omitted, contextual control must be clear: Bago umalis, pinatay ni Nilo ang ilaw naturally invites Nilo as the understood leaver, but a long sentence can create a dangling interpretation.
Pagkatapos niyang isumite ang aplikasyon, nakatanggap siya ng kumpirmasyon.
After she submitted the application, she received a confirmation.
In pagkatapos niyang isumite, ng-form niya is linked to the following verb and functions as its actor; patient ang aplikasyon remains the pivot of isumite.
Matapos suriin ng komite ang mga dokumento, inilabas nito ang pasiya.
After the committee examined the documents, it released the decision. (formal)
Matapos is common in formal and journalistic prose. The committee is ng-marked actor inside the patient/undergoer-voice subordinate predicate suriin, then resumed by nito in the main clause. This is a reference dependency across clauses, not verbal person agreement.
Starting and ending boundaries
Mula nang lumipat sila sa bagong gusali, mas maayos na ang serbisyo.
Since they moved to the new building, the service has become more orderly.
Completed lumipat supplies the starting boundary; the main adjectival clause describes the resulting state up to the present reference time.
Maghihintay kami rito hanggang matapos ang pagpupulong.
We will wait here until the meeting ends.
The waiting extends to the endpoint expressed by matapos ang pagpupulong. Hanggang sa matapos... is also standard and makes the boundary more explicit; shorter hanggang matapos... is common and neutral.
Negation can define an interval:
Hindi kami aalis hangga't hindi bumabalik ang drayber.
We will not leave until the driver returns.
Hangga't is the contracted form of hanggang at in this construction. The main negation and subordinate negation jointly express “not until”; translating each word separately produces misleading English logic.
Questions and temporal scope
Ano ang gagawin natin kapag hindi dumating ang suplay ngayong linggo?
What will we do if/when the supplies do not arrive this week?
Here kapag presents nonarrival as the relevant future occasion. In a genuinely uncertain condition, kung may be preferred. The boundary between temporal “when” and conditional “if” follows speaker commitment, not a simple tense rule.
—Kailan ninyo bubuksan ang bagong silid? —Pagkatapos mailagay ang mga kabinet at mesa.
—When will you open the new room? —After the cabinets and tables have been installed.
The answer is an ellipted temporal clause. Contemplated/result-oriented mailagay leaves the installer unexpressed because the question concerns the opening schedule, not agency.
Common Mistakes
1. Writing ng for temporal nang
❌ Umalis kami ng tumigil ang ulan.
Incorrect — a full temporal clause requires nang, not nominal marker ng.
✅ Umalis kami nang tumigil ang ulan.
We left when the rain stopped.
2. Using kung for every English when
❌ Kung bata pa ako, tuwing tag-araw kaming umuuwi sa Bicol.
Incorrect for a known past time frame — kung presents a condition rather than ‘when I was young.’
✅ Noong bata pa ako, umuuwi kami sa Bicol tuwing tag-araw.
When I was young, we went home to Bicol every summer.
3. Copying English after + subject without Filipino linking
❌ Pagkatapos siya nagsumite ng aplikasyon, umuwi siya.
Incorrect — pagkatapos requires an appropriate linked or clausal construction.
✅ Pagkatapos niyang isumite ang aplikasyon, umuwi siya.
After she submitted the application, she went home.
4. Using habang for non-temporal contrast only
❌ Mahilig sa kape si Dina habang mas gusto ni Leo ang tsaa.
Awkward English while-calque when no simultaneous time relation is intended.
✅ Mahilig sa kape si Dina, samantalang mas gusto ni Leo ang tsaa.
Dina likes coffee, whereas Leo prefers tea.
Key Takeaways
- Use nang for a specific past event frame and kapag for repeated, expected, or future occasions.
- Habang marks temporal overlap; bago/pagkatapos/matapos establish earlier and later relations.
- Mula nang introduces a starting boundary, while hanggang/hangga't introduces an endpoint.
- Temporal connectors do not replace aspect; each embedded and main predicate keeps its own aspectual viewpoint.
- Omitted actors must remain recoverable, and linked constructions such as pagkatapos niyang... require natural pronoun and marker forms.
