To Old English Backing and nasalization of West Germanic a and ā before a nasal consonant Loss of n before a spirant, resulting in lengthening and nasalization of preceding vowel The present and preterite plurals reduced to a single form A-fronting: WGmc a, ā → æ, ǣ, even in the diphthongs ai and au (see Anglo-Frisian brightening) palatalization of Proto-Germanic *k and *g before front vowels (but not phonemicization of palatals) A-restoration: æ, ǣ → a, ā under the influence of neighboring consonants Second fronting: OE dialects (except West Saxon) and Frisian ǣ → ē A-restoration: a restored before a back vowel in the following syllable (later in the Southumbrian dialects); Frisian æu → au → Old Frisian ā/a OE breaking; in West Saxon palatal diphthongization follows i-mutation followed by syncope; Old Frisian breaking follows Phonemicization of palatals and assibilation, followed by second fronting in parts of West Mercia Smoothing and back mutation loss of high vowels in syllable after stress Labial Dental Alveolar Post- alveolar Palatal Velar Glottal Nasal m (n̥) n (ŋ) Stop p b t d k ɡ Affricate tʃ (dʒ) Fricative f (v) θ (ð) s (z) ʃ (ç) (x ɣ) h Approximant (l̥) l j (ʍ) w Trill (r̥) r
