Breaking Down the Roots of Ineffable

"Every tone was a testimony against slavery, and a prayer to God for deliverance from chains. The hearing of those wild notes always depressed my spirit, and filled me with ineffable sadness," wrote Frederick Douglass in his autobiography. Reading Douglass's words, it's clear that ineffable means "indescribable" or "unspeakable." And when we break the word down to its Latin roots, we see how those meanings came about. Ineffable comes from ineffābilis, which joins the prefix in-, meaning "not," with the adjective effābilis, meaning "capable of being expressed." Effābilis comes from effārī, "to speak out," which in turn comes from ex- and fārī, meaning “to speak.”
