"Ineffable," "inenarrable," "indescribable" -- English has quite a few words for expressing that which can't be expressed. The prefix "in-," meaning "not," teamed up with Latin "enarrare" ("to explain in detail") to give us "inenarrable," and the same prefix joined with Latin "effabilis" ("capable of being expressed") to create "ineffable." English speakers have used "ineffable" since the 14th century, and "inenarrable" made its way into the language from French in the 15th century. "Indescribable" was a late arrival, relatively speaking -- it has only been with us since the 18th century.
