Phonology
Old Saxon does not participate in the High German consonant shift, and thus preserves stop consonants p, t, k that have been shifted in Old High German to various fricatives and affricates. The Germanic diphthongs ai, au consistently develop into long vowels ē, ō, whereas in Old High German they appear either as ei, ou or ē, ō depending on the following consonant. Old Saxon, alone of the West Germanic languages, consistently preserves Germanic -j- after a consonant, e.g. hēliand "savior" (Old High German: heilant, Old English: hǣlend, Gothic: háiljands). Germanic umlaut, when it occurs with short a, is inconsistent, e.g. hebbean or habbian "to have" (Old English: hebban). This feature was carried over into the descendant-language of Old Saxon, Middle Low German, where e.g. the adjective krank (sick/ill) had the comparative forms krenker and kranker. Apart from the E, however, the Umlaut is not marked in scripture.
