Temporal Clauses and Sequencing in Yoruba

Overview

Temporal clauses allow you to express when events happen in relation to each other. At the B1 level, mastering temporal connectors enables you to narrate sequences of events, describe timing relationships, and construct complex sentences about time. These connectors are essential for storytelling, giving instructions, and discussing schedules.

Key temporal connectors include: "nígbà tí" (when), "ṣáájú kí" (before), "lẹ́yìn tí" (after), "títí" (until), and "bí...ti" (as/while). Each introduces a subordinate clause that establishes a time frame for the main clause. The aspect markers within temporal clauses help specify the exact timing relationship.

Temporal clauses are crucial for narrative competence. When telling stories or recounting events, you need to sequence actions clearly. "Nígbà tí mo dé, ó ti lọ" (When I arrived, he had already gone) uses the temporal connector nígbà tí and the perfect marker ti to create a precise temporal picture. This level of temporal expression marks the transition from basic to intermediate Yoruba proficiency.

How It Works

Connector	Meaning	Pattern
nígbà tí	when	Nígbà tí + clause, main clause
ṣáájú kí	before	Ṣáájú kí + subject + tó + verb
lẹ́yìn tí	after	Lẹ́yìn tí + clause, main clause
títí	until	Main clause + títí + clause
bí...ti	as, while	Bí + subject + ti + ń + verb

Examples in Context

Yoruba	English	Note
Nígbà tí mo dé, ó ti lọ.	When I arrived, he had left.	When + perfect
Ṣáájú kí o tó lọ, jẹun.	Before you go, eat.	Before + command
Lẹ́yìn tí wọ́n ti jẹun, wọ́n lọ.	After they ate, they left.	After + perfect
Dúró títí mo fi padà.	Wait until I return.	Until
Bí mo ti ń lọ, mo rí i.	As I was going, I saw him.	While/as
Nígbà tí òjò bá dẹ́, a ó lọ.	When the rain stops, we will go.	When + conditional
Ṣáájú kí ó tó di alẹ́, a ti parí.	Before nightfall, we had finished.	Before + completion
Lẹ́yìn ọ̀sẹ̀ méjì, ó padà.	After two weeks, he returned.	After + time period
Títí di ọ̀la, a ó mọ̀.	Until tomorrow, we will know.	Until + future
Nígbà gbogbo tí mo bá rí i...	Whenever I see him...	Whenever

Common Mistakes

Confusing nígbà tí (when) with tí (relative marker)

• Wrong: Using tí alone for "when."
• Right: Use nígbà tí for temporal "when" and tí alone for relative "that/which."
• Why: Tí alone introduces relative clauses. Temporal "when" requires the full nígbà tí.

Wrong Verb Form After ṣáájú kí

• Wrong: Ṣáájú kí o lọ. (Before you go -- missing tó)
• Right: Ṣáájú kí o tó lọ. (Before you go.)
• Why: The construction ṣáájú kí requires tó before the main verb to complete the "before" meaning.

Not Using Aspect Markers for Sequence

• Wrong: Nígbà tí mo dé, ó lọ. (When I arrived, he went -- unclear timing)
• Right: Nígbà tí mo dé, ó ti lọ. (When I arrived, he had gone.)
• Why: Aspect markers (especially ti) within temporal clauses specify whether events are completed, ongoing, or anticipated relative to each other.

Practice Tips

1. Narrate your day in sequence: "Nígbà tí mo jí, mo wẹ̀. Lẹ́yìn tí mo wẹ̀, mo jẹun." (When I woke, I bathed. After I bathed, I ate.)
2. Practice before/after pairs: Take any two events and practice expressing them with both ṣáájú kí (before) and lẹ́yìn tí (after).
3. Add aspect markers for precision: Practice adding ti (perfect) and ń (progressive) within temporal clauses to create precise temporal relationships.
