How do you say christa in Irish Gaelic?

There isn't a direct, single-word translation of "Christa" in Irish Gaelic that captures the same meaning and sound. The name Christa is a variant of Christina, which itself derives from "Christ".

To translate the meaning, you'd use a name that reflects the "Christ" element, such as:

* Crísdín: This is a common Irish equivalent of Christina, leaning more towards the "Christ" origin. It's a more masculine-sounding diminutive.

* Críste: This is a more straightforward version.

Ultimately, the best translation depends on the context and how closely you want to match the sound or the meaning. There isn't a perfect equivalent.
