Solid, firm, enduring

Eithan is documented as a modern English spelling variant of Ethan, and more rarely of the Hebrew form Eitan. The underlying Hebrew name is traditionally glossed as solid, firm, strong, or enduring. Softened etymology emphasizes that steadfast cluster of meanings while noting that Eithan is an orthographic choice more than a separate ancient name.

Biblical Ethan the Ezrahite supplies the older narrative backdrop shared with the Ethan spelling.

Why the spelling matters on the chart

Eithan ranked 97 for U.S. boys in 2025. Its top-100 presence shows parents seeking the Ethan sound with a look that stands apart from the more common spelling—sometimes reflecting Hebrew or Spanish-influenced orthographic taste.

Pronunciation generally matches Ethan: EE-thun.

Practical advice

Expect to clarify spelling more often than pronunciation. Sibling sets may include Noah, Leah, or Maya. Compared with Ethan, Eithan trades ease for distinctiveness; compared with Eitan, it may feel more anglicized.

Pick Eithan if the enduring meaning and unique letters both matter, and you are ready for the occasional spelling correction.

Same endurance, different letters

Eithan is for parents who love Ethan’s solid/firm/enduring Hebrew meaning but want a visual twist. The tradeoff is real: more uniqueness, more spelling moments at coffee shops and clinics.

If that tradeoff feels worth it, you are in growing company. Rank ninety-seven in 2025 proves the variant spelling has enough momentum to stand on the national boys’ list beside its more common sibling.
