Alexithymia (pronounced /əˌlɛksəˈθaɪmiə/) from the Ancient Greek words λέξις (lexis, "diction", "word") and θυμός (thumos, "soul, as the seat of emotion, feeling, and thought") modified by an alpha-privative—literally "without words for emotions"—is a term coined by psychotherapist Peter Sifneos in 1973 to describe a state of deficiency in understanding, processing, or describing emotions.
