αὐτῶν, (auton) in Romans 3:13: Genitive Plural Masculine

Pronoun: the form points back to persons or things already in view, rather than naming them again.

Genitive: the form usually marks relationship, possession, source, or association, and here it ties the parts of the body to the people in view.

Plural: the form is grammatically plural in this occurrence, so it refers to more than one person or thing.

Masculine: the form is masculine in grammar, but that is a language feature and does not by itself make a theological gender claim.

The form attaches to the body-part references in the phrases ὁ λάρυγξ αὐτῶν and ταῖς γλώσσαις αὐτῶν.

The genitive form most naturally depends on the nearby body terms and identifies whose throat and tongues are being described.

It functions as a possessive or relational reference, linking the imagery to the people being described in the quotation.

It does not change the meaning of the noun itself, and it does not by itself determine the scope of the moral charge in the verse.

Moderate: The genitive pronoun ties the speech imagery to the people described in the indictment.

Possessive or relational genitive pronoun. marks whose throat and tongues are being described. Attached to the throat and tongues in Romans 3:13. Governed by the nearby body-part noun phrases. The pronoun tracks the group under indictment and should not widen the claim beyond the quotation context.

Whose throat and tongues are being described? The pronoun points to the people under discussion in the indictment.

Direct: The genitive pronoun directly supports wording such as 'their throat' and 'their tongues.'

The pronoun depends on the surrounding quotation for its referent. The genitive relation is local and should not be made to carry the entire moral indictment alone.

Pronoun grammar proves the full scope of the indictment: The pronoun marks reference; Paul's argument and quotation supply the scope. masculine plural excludes women by grammar alone: Masculine plural is grammatical form in the quotation context and should not be overread.

The witness reads αὐτῶν in Romans 3:13 within the phrase ἀνεῳγμένος ὁ λάρυγξ αὐτῶν, ταῖς γλώσσαις αὐτῶν.

The lemma αὐτός is a common pronoun that can refer back to previously named or implied referents, and here it points back to the people under indictment.

The genitive plural fits the surrounding nouns by showing whose throat and tongues are in view, so the grammar supports the collective portrait already unfolding in the verse.

The verse presents a figurative description of corrupt speech and harmful character, and this pronoun helps locate that description in the people addressed by the quotation.

Within Romans 3, the form serves the larger argument that Scripture exposes human speech and conduct as part of the need for divine remedy.

In teaching or translation notes, the form can be explained as a simple reference marker: these are their throats, their tongues, and their conduct.

Do not infer from the masculine grammar that the text is making a male-only statement, and do not build a separate doctrine from the case ending alone.
