The nominative form is part of the direct question asking whether the hearer is Elijah, so it functions as the label of identity in the inquiry.

It supplies the name under discussion in the question and helps the line read as a proposed identification, not as a statement that Elijah is present in the scene.

It does not by itself decide the speaker's belief, nor does the case ending force a hidden doctrinal meaning beyond the question being asked.

Moderate: The nominative personal name supplies the proposed identity in the question, 'Are you Elijah?'

Nominative personal name in an identity question. names the identity being proposed and denied in the dialogue. Attached to the question asking whether the hearer is Elijah. Governed by the verb of being in the direct question. The nominative form supports the identity question without deciding the theological background by itself.

Which identity is being proposed? The question proposes Elijah as the identity under discussion.

Supporting: The nominative form supports the identity-question rendering, 'Are you Elijah?'

The name's case supports the question's identity grammar, not a separate assertion that Elijah is present. Masculine gender is grammatical and should not be made theological.

Nominative case proves the answer: The case supports the question; the dialogue supplies the answer. name form carries hidden doctrine: The form names Elijah in the question, while Scripture context governs expectations about Elijah.

The witness reads 'Ἠλίας' in John 1:21 within the question 'Ἠλίας εἶ σύ;'.

The lexeme is Elijah, the prophet named by the lexicon artifact as Helias, i.e. Elijah.

In context, the nominative form works with the verb 'are you' to frame Elijah as the proposed identity being queried.

The verse asks whether the questioned man is Elijah, and the form helps present that claim as a direct identity question.

The lexicon marks this as a canonical anchor, so the form here connects the local question to the broader biblical figure of Elijah without adding extra claims.

For readers, the grammar makes the dialogue crisp and immediate, showing that the speakers are probing John's identity in terms familiar to the audience.

Do not derive from the nominative case any claim that Elijah is the subject of the whole verse, or that grammatical gender itself carries theological meaning.
