There isn't a direct, universally accepted translation of the name Zayden into Irish. Irish names are often based on meaning, and Zayden doesn't have a clear equivalent meaning in the Irish language. To create an Irish-sounding name, you'd need to find an Irish name with a similar sound or a meaning that resonates with you. You might consider names like:
* Zeain: This uses a similar sound. However, it's a modern creation and not a traditional Irish name.
* Séadna: This is a traditional Irish name, but the pronunciation is quite different.
Ultimately, any attempt to translate "Zayden" into Irish will be a creative interpretation rather than a true translation.
