Synonyms of 'anyway'
usage note:The single-word form anyway should not be used as an alternative to any way, because the meanings are very distinct. Anyway is an adverb meaning `nonetheless' or, in a different sense, `besides'. Any way, however, means `by any means' or `in any manner'. The distinction can be seen in the following examples: it wasn't my job, but I helped anyway means `in spite of this fact', while we will help in any way we can means `any manner at all'.
