The short answer
Eithan is a masculine name that Behind the Name defines in one line: a "variant of Ethan or (rarely) Eitan." Its usage is tagged English (modern) and Hebrew (rare). The meaning therefore belongs to Ethan, which Behind the Name's Ethan entry derives from the Hebrew name ʾEṯan meaning "solid, enduring, firm", borne in the Old Testament by minor figures including the wise man Ethan the Ezrahite. Ethan is pronounced EE-thən in English; no separate pronunciation is given for Eithan. In the United States Eithan ranked #97 for boys in 2025.
Meaning and etymology
The Eithan entry on Behind the Name reads, in full, "Variant of Ethan or (rarely) Eitan." It lists Ethan (English) and Eitan and Eytan (Hebrew) as variants, and Ethan (Biblical, Biblical Latin, French), Aithan (Biblical Greek), 'Etan (Biblical Hebrew) and Izan (Spanish) as forms in other languages. For the meaning, Behind the Name's Ethan entry gives "From the Hebrew name אֵיתָן (ʾEṯan) meaning 'solid, enduring, firm'", and notes that in the Old Testament the name is borne by a few minor characters, including Ethan the Ezrahite, supposedly the author of Psalm 89. The Eitan entry was not consulted in this pass.

What the name feels like
Eithan sounds exactly like Ethan but looks different on the page: the extra i gives it a slightly Hebrew or continental cast. It reads as a fresh take on a very familiar classic rather than a new name in its own right.
Style tags: variant spelling, Hebrew, biblical, two syllables, modern
Editorial interpretation: These style impressions are editorial judgment, not linguistic fact. The identification with Ethan and the 'solid, enduring, firm' gloss are Behind the Name's; the observation about how the spelling 'reads' is opinion.
