everichon

• everchon, everechon, everich on, everychon, everychone
• everychoon, everyschon, evirichon (Late Middle English) eaver euchan (AB language)
• everilcan, everilc on (East Anglia, East Saxon); evrichen (Kent); everech on (Southern); everuchen, everuchon (West Midland)
• everilkan, ever-ilkan, everilkane, everilkon, ever-ilkone (Northern); evirilkane, evyrilkane, ewyre ilkayn (Early Scots)

From everich, variant of every (“every”) +‎ on (“one”); the loss of /t͡ʃ/ seen in every is avoided since it is protected by the following vowel of on.

The final syllable of Kentish Middle English evrichen may either reflect vowel reduction or a parallel formation from ene, enes (“once”).
