Etymology : Wherewithal has been with us in one form or another since the 16th century. It comes from our still-familiar word where, and withal, a Middle English combination of with and all, meaning “with.” Wherewithal has been used as a conjunction meaning “with or by means of which” and as a pronoun meaning “that with or by which.” These days, however, it is almost always used as a noun referring to the means or resources—especially financial resources—one has at one’s disposal.
