An archaic form meaning 'as well' or 'equally,' used in Middle English texts.
From Old English combining 'al' (all) with 'swa well' (as well), a variant spelling of 'aswell' that appears in medieval manuscripts before modern English standardized the phrase.
This word shows how English spelling wasn't standardized before the printing press—writers just spelled words however seemed right to them, so 'as well' appeared as 'alsweill,' 'aswell,' 'aswele,' and dozens of other variations.
