Modeling Intelligibility of Written Germanic Languages: Do We Need to Distinguish Between Orthographic Stem and Affix Variation?

Abstract

We measured orthographic differences between five Germanic languages. First, we tested the hypothesis that orthographic stem variation among languages does not correlate with orthographic variation in inflectional affixes. We found this hypothesis true when considering the aggregated stem and affix distances between the languages. We also correlated the stem and affix distances within the cognate pairs in each language pair. We found low correlations, the lowest of them being not significant. Second, we tested the hypothesis that orthographic stem variation among languages is larger than orthographic variation in inflectional affixes. This hypothesis was also found to be true. Orthographic distance is likely to be a potential predictor of written intelligibility, but our results suggest that when modeling written intelligibility, a distinction needs to be made between stem and affix distances.
