The word "lassitude" originates from Latin lassitūdō, derived from lassus (meaning "weary" or "tired"). The morpheme lass preserves the core idea of weariness, while -itude (a suffix borrowed from Latin -tūdō) forms abstract nouns denoting states or conditions. Over time, the term evolved in Middle French as lassitude before entering English in the 16th century, retaining its original sense of exhaustion or languor.
