λύχνου (luchnou) in Revelation 22:5: Noun Genitive Singular Masculine

Noun: the word names a thing, here a lamp, and it contributes a concrete image rather than an action or modifier.

Genitive: the form usually marks a dependent relation, and here it most naturally fits a phrase of need or associated source in the clause.

Singular: the form is grammatically singular in this occurrence, so it speaks of one lamp as a unit of reference.

Masculine: the noun belongs to the masculine grammatical class, which is a language feature and does not by itself imply a masculine theological claim.

χρείαν οὐκ ἔχουσι

The genitive λύχνου is linked to the idea of lacking need, so it helps specify what kind of lamp-related provision is in view.

It functions as a dependent genitive that works with the surrounding phrase about not needing a lamp and sunlight because God gives light.

It does not by itself say that a lamp is the subject or the main action, and it does not force a hidden theological meaning beyond the clause.

High: The genitive noun names lamp as one ordinary light source no longer needed because the Lord God gives light.

Genitive singular noun completing a need expression. identifies lamp as one object of the denied need. Attached to the no-need-of-a-lamp phrase in Revelation 22:5. Governed by the expression of need in the clause. The form supports the contrast between ordinary light sources and divine illumination.

What ordinary source of light is no longer needed? The genitive identifies a lamp as part of what is no longer needed.

Direct: The form directly supports wording such as "need of a lamp."

The genitive works with the need expression and should not be treated as the subject of the clause. The image belongs to the vision of divine light and should not be reduced to the object lamp alone.

Genitive object becomes the main theological subject: The lamp is named as unnecessary; the clause centers on the Lord God giving light. symbolism is built from the case ending alone: The vision and contrast with divine illumination supply the interpretive force.

In the provided text of Revelation 22:5, λύχνου appears in the phrase about not having need of a lamp and the sun's light.

The lemma λύχνος names a lamp or portable light source, and the lexicon summary also allows a figurative extension when context supports it.

Here the genitive singular form sits after the expression of need, so it contributes to the clause that denies the need for lamp light in that setting.

The verse presents a state where ordinary night lighting is unnecessary because the Lord God gives light to them, and that light replaces what lamps and sunlight would normally supply.

This fits the passage's larger theme of final divine illumination and the removal of darkness from the holy city.

For readers and teachers, the form helps show that the verse is not mainly about a physical lamp as an object, but about the sufficiency of God's light in the scene.

Do not derive that the form alone defines the whole symbolism, settles every syntactic option, or turns grammatical gender into a doctrinal statement.
