Impecuniously → It is formed from "im-" (meaning not) and "pecunia" (from Latin, meaning money) and the suffix "-ously" (meaning in a manner). The word describes a state of being without money or being poor.
Think of 'not having money' ('im-' means not, and 'pecunia' means money) to remember that 'impecuniously' refers to being in a state of poverty.
