Unicode Restoration
Njǫrðr
Restored stress, length, and script
Modern ASCII
njordr
Plain-ASCII fallback
Njǫrðr is Tier 1 because the Unicode restoration preserves the distinctive Norse vowel ǫ and the voiced dental fricative ð — distinctive letters the ASCII form loses. Old Norse stress is initial and strong, yet it is not encoded by an acute; the registrable form Njǫrðr records the name's characteristic Norse orthography. Reconstruction follows Cleasby & Vigfusson, An Icelandic-English Dictionary (1874); Zoëga, A Concise Dictionary of Old Icelandic (1910); and Ranke & Hofmann, Altnordisches Elementarbuch, 5th ed. (de Gruyter, 1988).
