An obsolete or extremely rare term meaning aside or to one side; separated or removed from a place.
Possibly from ask- (Old Norse á, on) + -ile (a directional suffix similar to -ile in aisle). This appears to be a variant of similar directional terms that mostly disappeared from English.
This word is so obscure it barely appears in any historical texts—it's like discovering the fossil remains of English's lost directional vocabulary that people once used but gradually replaced with simpler words!
