Eithan

Firm, enduring

Eithan is a masculine name with Hebrew roots, related to Ethan and Eitan. Its meaning, “firm” or “enduring,” offers an image of strength that lasts rather than a moment of force. That can give the name a quietly resolute feel. The spelling Eithan adds an i to Ethan. It can look contemporary while retaining the older Hebrew connection; the extra letter changes the written shape, not the underlying meaning. If that balance appeals to you, it is worth considering Eithan as a spelling in its own right rather than treating the i as incidental. One English pronunciation is /ˈiːθən/, roughly EE-thuhn, with the th of thin. This is an option, not a pronunciation rule for everyone named Eithan. When choosing the name, settle the sound as well as the spelling; when meeting someone called Eithan, follow their own pronunciation.

Etymology: A variant of Ethan, and less often of Eitan, from Hebrew אֵיתָן (ʾEṯan). The Hebrew sense concerns firmness and lasting strength.
