Oxford invariably spelled modern English "ought" as "oft" or "ofte" - positively revealing that he spoke with a provincial dialect. Less surprisingly, he also used "oft" to mean "often" (see words with asterisks).
Oxford used the spelling "ought" to mean "out", but he also spelled this word "out", "owt", and "owte" (see wordlists in headpage).
