More about catalyst
Catalyst was originally (at the beginning of the 20th century) a technical term used in chemistry, meaning 鈥渁 substance that causes or accelerates a chemical reaction without itself being affected.鈥� By the early 1940s, the English poet and critic Sir Herbert Read extended the sense to a poet as a person who precipitates an event or change: “The catalyst [the poet] is unchanged, unabsorbed; its activity therefore not acknowledged.” Catalyst is irregularly formed from the Greek noun 办补迟谩濒测蝉颈蝉 鈥渄issolution, tearing down (especially of governments), a derivative of the verb 办补迟补濒媒别颈苍 鈥渢o pull down, destroy, dissolve (a political system), and the (originally Greek) agent suffix –ist. 碍补迟补濒媒别颈苍 is a compound of the Greek preposition and prefix 办补迟谩, kata– 鈥渄own, against, back鈥� (usually spelled cata– in English) and the simple verb 濒媒别颈苍 鈥渢o loose, untie, release, solve, resolve.鈥�
