νόμου (nomou) in Romans 3:21: Noun Genitive Singular Masculine

Noun: the word names a reality here, namely law, and it can point to law in a general sense or to the Mosaic law in context.

Genitive: the form usually marks a relationship to another word, and here it helps express the sense of being apart from law.

Singular: the form is grammatically singular in this occurrence, so it presents law as a singular category or whole.

Masculine: the noun belongs to the masculine grammatical class, which is a lexical feature and not a claim about personal or theological gender.

χωρὶς

The genitive noun follows the preposition and gives the phrase its sense of separation, so the line reads as righteousness being revealed apart from law.

It functions as the object of the separation idea and contributes to the contrast between God's righteousness and law as a basis for that revelation.

It does not by itself say law is absent from God's plan, and it does not turn the noun into a subject or a verbal idea.

High: The genitive after χωρὶς supports the key contrast between righteousness apart from law and witness by the law and prophets.

Genitive noun governed by χωρὶς. marks separation or apartness in the statement about God's righteousness being revealed. Attached to χωρὶς νόμου. Governed by the preposition χωρὶς. The form must be held together with the same verse's witness language about the law and the prophets.

How is God's righteousness related to law in this line? The phrase says it is revealed apart from law as the basis, while the verse still says the law and prophets witness to it.

Direct: The form directly supports wording such as apart from law.

Apart from law does not mean without Scriptural witness, since the same verse mentions the law and prophets bearing witness. The genitive phrase should not be isolated from the verse's continuity statement.

Apart from law means the law has no witness value: The phrase marks basis or separation in the clause, while the same verse preserves the law's witness role.

The witness reads νόμου in Romans 3:21, within the clause νυνὶ δὲ χωρὶς νόμου δικαιοσύνη Θεοῦ πεφανέρωται, μαρτυρουμένη ὑπὸ τοῦ νόμου καὶ τῶν προφητῶν.

The lemma νόμος means law, and in this context the surrounding wording strongly supports law as a covenantal or Mosaic reference rather than a new lexical sense.

The genitive with χωρὶς marks distance or apartness, so the sentence says God's righteousness has now been revealed apart from law as the operative basis, while still being witnessed by law and the prophets.

Paul presents God's righteous action as newly disclosed without depending on law, yet not in conflict with Scripture, since the law and the prophets bear witness to it.

This fits the wider biblical pattern in which God's revelation is continuous with prior witness, even when its saving manifestation is not grounded in law-keeping.

For teaching, the form helps readers hear both distinction and continuity: apart from law as a ground, but not apart from the witness of the law.

Do not infer that the form alone decides every theological use of law, or that it cancels law's witness, value, or covenantal role.
