    Usage notes

    The etymological antonym is (m) (from Latin) (compare (m)/(m) for “first/last”). This is now no longer used, however, and there is no corresponding antonym. Typically either (m) or (m) are used, but these form different pairs – (m)/(m) and (m)/(m) – and are more formal than prior . When an opposing pair is needed, these can be used, or other pairs such as (m)/(m) or (m)/(m).
