"Antithetical" and "antithesis" entered English in the 16th century. Their etymological paths pass through Late Latin and ultimately lead to Greek (the Greek words "antitithenai" and "antithesis" mean "to oppose" and "opposition," respectively). The oldest sense of the English "antithesis" refers to a language pattern that contrasts parallel ideas, as in "action, not words" or "they promised freedom and provided slavery." "Antithetical" can mean "constituting or marked by such language patterns." For example, you could say "The phrase 'action, not words' is an antithetical construction." It is more common in current use, however, for "antithesis" to mean "the exact opposite" and for "antithetical" to mean "directly opposite."
