Niamh is pronounced NEEV — a single syllable. The spelling confuses English speakers because Irish uses different conventions from English. In Irish, mh at the end of a word (or before a consonant) makes a "v" sound (in Munster and Connacht dialects) or a "w" sound (in Ulster). The "ia" makes a long "ee" sound. Put together: N + ee + v = NEEV.
In some Ulster dialects, the "v" sound softens further, giving something closer to NEEV with a very light final consonant. But NEEV is the standard pronunciation taught in schools and used in media.
Niamh derives from the Old Irish word níam, meaning brightness, lustre, or radiance. The root relates to shining, glistening surfaces — the kind of light reflected off water or gold or a person of striking appearance. The name carries a sense of outward brilliance, of someone whose presence illuminates a room.
The word appears in early Irish poetry as an adjective for things that gleam or shine — a polished sword, a bright sky, a person of exceptional beauty. It is one of the oldest strata of Irish names, appearing in texts from the eighth and ninth centuries.
The name is related to the Welsh nef (heaven, sky) through the common Celtic root, suggesting a Proto-Celtic original meaning of something like "brightness of the sky" or "heavenly radiance."
The most famous Niamh in Irish mythology is Niamh Chinn Óir — Niamh of the Golden Hair — who appears in the Fenian Cycle, the body of tales centered on Fionn Mac Cumhaill (Finn McCool) and his warrior band, the Fianna.
In the tale of Oisín in Tír na nÓg, Niamh arrives from the sea on a white horse, drawn to the mortal world by her love for Oisín, the poet-warrior son of Fionn Mac Cumhaill. She invites Oisín to come with her to Tír na nÓg — the Land of Eternal Youth — where there is no sickness, no old age, and no death.
Oisín accepts and they ride together across the sea to Tír na nÓg. There they live for what feels like three years, though three centuries pass in the mortal world. Eventually Oisín becomes homesick for Ireland and asks to visit. Niamh allows him to go but warns him not to dismount from his white horse, or he will never be able to return to Tír na nÓg.
Oisín returns to find Ireland changed beyond recognition — the Fianna are long dead, the old Ireland is gone. When he tries to help some men lift a stone, he falls from his horse. He immediately ages three centuries and dies. The story is one of the great tragic tales of Irish mythology — a meditation on time, loss, and the impossibility of returning to what has passed.
In Irish mythology, Niamh represents a recurring figure: the beautiful woman from the Otherworld who chooses a mortal man and invites him to leave the human world. These figures — called síde women — appear throughout the mythological and heroic cycles. They are always described in terms of light and radiance: gold hair, white skin, luminous eyes. The name Niamh, meaning brightness, was the perfect name for this kind of figure.

Like Aoife and other purely Gaelic names, Niamh was largely absent from official records during the period of English administration when anglicised names were used in documents. In nineteenth-century Irish parish registers and civil records, a girl named Niamh at home might appear as Neve, Nieve, or simply have her name recorded as a phonetic approximation.
The revival of Irish names in the twentieth century brought Niamh back into official use. It appears consistently in Irish birth registrations from the 1930s onward, and became a mainstream choice by the 1970s.
If you are researching Irish ancestry and your family tree shows a "Neve" or "Nieve" in the nineteenth century, it is worth considering whether the actual Irish name was Niamh.
