Transparency and blocking in Old Norwegian height harmony
Jade Jørgen Sandstedt
Abstract This paper provides a new phonological and philological analysis of previously unexplained disharmonic patterns in Old Norwegian height harmony. Old Norwegian displays cross- linguistically rare forms of blocking and transparency, which under traditional assumptions of Old Norwegian vowels and vowel harmony are both phonologically and orthographically irregular. I show that these patterns make perfect phonological sense if we reinterpret the Old Norwegian neutral vowels æ–ǫ as [−low, −ATR] /E, O/ and assume that Old Norwegian height harmony was relativized to [high] contrastive visibility and bounded by high-sonority elements, resulting in the transparency of [high] non-contrastive items and blocking by high- sonority [+low] vowels. This featural interpretation fits with the later diachronic development of Old Norwegian vowels and additionally helps explain patterned spelling variation found in both roman and runic writing.
