You may right.
The point I was trying to make had to do with the introduction of the term Passover which replaced the commonly used Easter. They were translated from the same Greek word, which you also pointed out pask. That would be like some Bible words that were not translated because they couldn't think of an English equivalent. A lot of place names are like that as is the common Selah in the Psalms.
easter isn't "translated" from Pascha.
it is substituted.
it is found in the wessex translations because, as Bede clearly put, it was the pre-existing name of the season among the pagans there during which Pascha takes place.
easter has zero linguistic relationship to Pascha.
