Passive Constructions (Ni...sí) in Yoruba

Overview

Yoruba does not have a morphological passive voice like European languages. At the B1 level, understanding how Yoruba achieves passive-like meanings is important because learners often look for a passive construction and cannot find one. Instead, Yoruba uses several strategies to express what English conveys with passive voice: impersonal subjects, focus constructions, and the indefinite agent "wọ́n" (they/one).

The most common passive strategy uses "wọ́n" (they) as an indefinite agent: "Wọ́n kọ ilé náà" (They built the house = The house was built). Here, "wọ́n" does not refer to specific people but functions like English "one" or the French "on." Another strategy uses "a" (one/we, general): "A ṣe iṣẹ́ náà" (One did the work = The work was done).

Understanding these alternatives to passive voice is important for reading and listening comprehension, as they appear frequently in news, storytelling, and formal discourse. Rather than looking for a passive morpheme, recognize these active constructions with indefinite subjects as Yoruba's way of defocusing the agent.

How It Works

Strategy	Pattern	Example	Passive Equivalent
Wọ́n (indefinite they)	Wọ́n + V + O	Wọ́n kọ ilé náà.	The house was built.
A (indefinite one)	A + V + O	A ṣe iṣẹ́ náà.	The work was done.
Focus/topicalization	Object + ni + wọ́n/a + V	Ilé náà ni wọ́n kọ́.	It's the house that was built.

Key principle: The agent is not removed but made indefinite or unspecified.

Common Mistakes

Looking for a Passive Morpheme

• Wrong: Searching for a specific passive marker or verb form.
• Right: Recognize that Yoruba uses active constructions with indefinite agents (wọ́n, a) for passive meaning.
• Why: Yoruba genuinely does not have morphological passive. Understanding this typological difference is key.

Confusing Definite wọ́n (they) with Indefinite wọ́n (one/people)

• Wrong: Interpreting "Wọ́n kọ ilé náà" as "Specific-they built the house."
• Right: In context, "wọ́n" is often indefinite, meaning "the house was built" (by unspecified agents).
• Why: Context determines whether wọ́n refers to specific people or functions as an indefinite agent.

Trying to Remove the Subject Entirely

• Wrong: Kọ ilé náà. (Built the house -- no subject)
• Right: Wọ́n kọ ilé náà. (They built the house = It was built.)
• Why: Yoruba sentences require a subject. Use wọ́n or a as the indefinite subject.

Practice Tips

1. Convert English passives to Yoruba: Take passive sentences and restructure them with wọ́n: "The book was read" → "Wọ́n kà ìwé náà."
2. Practice with news-style sentences: News reports frequently use passive equivalents: "Wọ́n ti mú olè náà" (The thief has been caught).
3. Distinguish definite and indefinite wọ́n: In conversations, practice recognizing when wọ́n refers to known people versus unknown/general agents.
