ποῖος

of what sort

Definition

ποῖος is an interrogative adjective meaning 'of what sort,' 'what kind of,' or 'which.' It is used to ask qualitative questions about the nature, character, or identity of something or someone. In the New Testament, it often probes the essence or quality of an action or thing, as in Matthew 21:23 where the chief priests ask Jesus, 'By what authority are you doing these things?' It can also function in a more general sense of 'what,' as seen in Matthew 24:42–43, where it asks about the timing of an event: 'what kind of watch' the homeowner would have kept.

Biblical Usage

This word appears 32 times in the New Testament, primarily in the Gospels (especially Matthew and Luke) and Acts. It is used in direct questions, often in dialogue to challenge or seek clarification. For example, in Matthew 22:36, a lawyer asks, 'Which (ποῖος) commandment is the greatest?' In Acts 7:49, it appears in a quotation from Isaiah. Its usage consistently focuses on discerning quality, type, or specific identity within a set.

Etymology

Derived from the Greek root πο- (related to the interrogative pronoun τίς, 'who/what'), ποῖος is formed with the suffix -ιος, giving it an adjectival, qualitative force. It is cognate with other Greek interrogatives like πόθεν ('from where') and πότε ('when'), all used to seek specific information. Its meaning remained stable as 'of what sort' from classical through Koine Greek.

Semantic Range

ποῖος is theologically significant because it often introduces questions that probe the nature of divine authority, moral responsibility, and eschatological expectation. In passages like Matthew 21:23–27, it highlights confrontations over Jesus' authority, forcing listeners to consider the source and quality of spiritual power. Understanding this word enriches reading by showing that biblical questions often seek not just facts, but the essential character of God's actions and human responses.

In the Greco-Roman world, ποῖος was a common interrogative in philosophical and legal discourse, used to classify and define. When New Testament characters employ it, they are often engaging in a style of debate familiar in ancient dialogues, seeking to categorize actions or teachings within accepted frameworks of law, wisdom, or authority.

τίς (tis, G5101) — asks 'who?' or 'what?' primarily for identity or quantity, not quality. ποταπός (potapos, G4217) — means 'of what country or kind,' often expressing astonishment at nature or origin.
