We've used "effusive" in English to describe excessive outpourings since the 17th century. In the 1800s, geologists adopted the specific sense related to flowing lava-or to hardened rock formed from flowing lava. "Effusive" can be traced 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 he or she speaks effusively. Liquids can effuse as well (as in "water effusing from a pipe").
