• wīġbed, wēafod

From pre-Old English *wīohbēod, equivalent to wēoh (“idol, image”) +‎ bēod (“offering stage, dish”). The replacement of /b/ with /f/ is motivated by the fact that medial /b/ historically developed to [v], and the word was no longer felt to be a compound.

• IPA^(key): /ˈwe͜oː.fod/, [ˈwe͜oː.vod]

wēofod n

1. altar

     Also, at a certain hall, the holy man slipped on the high steps at the holy altar, so that almost his whole body became bruised; but in the night, God restored him to full health through his holy angel.
