Phonological history of Old English ( The voiced velars [] and [] were still allophones of a single phoneme (although by now [] was the form used in initial position); similarly, their respective palatalized reflexes [d] and [j] are analyzed as allophones of a single phoneme /j/ at this stage, This /j/ also included older instances of [j] which derived from Proto-Germanic /j/, and could stand before back vowels, as in eong /jun/ ("young"; from PGmc *jungaz) and eoc /jok/ ("yoke"; from PGmc *juk).
