What does from off himself mean?

"From off himself" is a very archaic and uncommon phrase. It is not used in modern English.

It likely means something similar to:

* "On his own accord"

* "By himself"

* "Of his own volition"

Example:

* Old English: "He went from off himself to the forest."

* Modern English: "He went to the forest on his own."

It's important to note: This phrase is so outdated that it would likely be considered incorrect or misunderstood in modern English.
