Insuperable first appeared in print in the 14th century, and it still means now approximately what it did then. "Insuperable" is a close synonym to "insurmountable." In Latin, superare means "to go over, surmount, overcome, or excel." The Latin word insuperabilis was formed by combining the common prefix in- (meaning "not" or "un-") with "superare" plus "abilis" ("able"). Hence insuperabilis means "unable to be surmounted, overcome, or passed over," or more simply, "insurmountable." The word insuperabilis was later anglicized as "insuperable." Related words such as "superable," "superably," and even "superableness" have also found a place in English.
