Meaning

Ruler element in the cited Irish account; the full derivation remains uncertain

The guide connects the name with the older Irish flaith element, interpreted in terms of rulership. This supports a qualified name-element account rather than an exact translation of the entire name. Proposed interpretations of the first element are not assigned here.

Origin

Documented Irish given-name tradition

Gaelchultúr’s Irish-language baby-name guide explicitly includes this spelling in the Iarlaith name account. This records a naming tradition, not a bearer’s ancestry or one settled prehistoric derivation.

English pronunciation

Not yet published for this spelling.

Gaelchultúr explicitly links Iarlaith with Iarfhlaith; Woulfe’s historical personal-name entry pairs Iarfhlaith with Jarlath.
