Origin of excrescenceMiddle English from Latin excrēscentia from neuter pl. of excrēscēns excrēscent- present participle of excrēscere to grow out ex- ex- crēscere to grow ; see ker-2 in Indo-European roots.
Middle English, early 15th century, in sense “(action of) growing out (of something else)”. From Latin excrescentia (“abnormal growths”), from excrescentem, from excrēscere, from ex- (“out”) (English ex-) + crēscere (“to grow”) (English crescent). Sense of “abnormal growth” from 1570s, from earlier excrescency (1540s in this sense).
