Effusive History Is Overflowing

English speakers have used effusive to describe excessive outpourings since the 17th century. Its oldest and still most common sense relates to the expression of abundant emotion or enthusiasm, but in the 1800s, geologists adopted a specific sense characterizing flowing lava, or hardened rock formed from flowing lava. Effusive can be traced, via the Medieval Latin adjective effūsīvus ("generating profusely, lavish"), to the Latin verb effundere ("to pour out"), which itself comes from fundere ("to pour") plus a modification of the prefix ex- ("out"). Our verb effuse has the same Latin ancestors. A person effuses when speaking effusively. Liquids can effuse as well, as in "water effusing from a pipe."
