Roonagh as a Baby Name. Meaning and Origin of Roonagh

What is the meaning of the name Roonagh ?

The baby name Roonagh is a Female name , 2 syllables long and is pronounced ROO-nə (IPA: /ˈruːnə/).

Roonagh is Icelandic, Irish in Origin.

Roonagh is an Irish Gaelic feminine name most plausibly reflecting the Gaelic form Rúnach, built on rún - “secret, mystery,” and by extension “beloved, darling” in endearments like a rúin - plus the adjectival suffix -ach. It is often interpreted as “secret one,” “keeper of secrets,” or “beloved confidante.” The spelling with -agh follows common Anglicization patterns for Irish -ach, yielding a soft final sound in English. While sometimes compared with Scandinavian Rúna/Runa (from Old Norse rún “rune, secret”), Roonagh is rooted in the Irish lexicon and tradition.

The word rúnach appears as a descriptive byname in early Irish sources and survives widely in placenames, including Roonagh Pier in County Mayo, reinforcing its Gaelic pedigree. As a given name, Roonagh is rare in historical records but has seen modest modern revival among families seeking distinctive Irish heritage names. Variants include Rúnach (standard Irish), Rúna/Runa, and Roona; related but etymologically separate are Ríona (from Regina) and Ronan/Rónán.
