Inherited from Northern Middle English Acom, Akom, from Old English ācum, dative singular of āc (“oak”). The traditional local pronunciations reflect the regular development of word-initial Old English /ɑː/ to /ja~jɛ/ that occured in most traditional dialects of the North of England (north of the Humber–Lune line); compare yan (“one”).
