Forms
effundō (present infinitive effundere, perfect active effūdī, supine effūsum); third conjugation[1] It is also spelled ecfundō.[2][3] Paulus' epitome of Festus gives exfūtī for effūsī.[2]
Etymology
It is formed from Latin ex- (“out”) + fundō (“to pour”).[2][3][1] De Vaan derives fundō from Proto-Italic *χund-e/o-, from Proto-Indo-European *ǵʰu-n-d- (“to pour”), a nasal present of the root of Ancient Greek χέω (khéō, “to pour”), Gothic 𐌲𐌹𐌿𐍄𐌰𐌽 (giutan, “to pour”) and Sanskrit जुहोति (juhóti, “pours, sacrifices”); the initial /f/ for PIE /gʰ/ is found only in this verb.[4]
Earliest recorded meaning
Plautus has effunde cito hoc in barathrum, “pour this quickly down the pit”, of wine poured down the throat.[2][3]
Semantic evolution
Effundere is “to pour out” liquids, of rain “to pour down”, and “to shed” tears or blood (Cicero of the tears shed for him in his troubles).[2][1] Rivers sē effundunt, flow into the sea or overflow.[2] It is also to send forth light or breath, and spīritum or animam effundere is “to breathe one's last”.[2] Of words it is “to utter, pour forth” (Virgil: tālīs effundit pectore questūs, “such complaints he poured from his breast”), and of feelings “to give vent to”.[2][1]
It means to let loose, and in the passive of crowds and armies “to stream out”; to squander money or strength; to throw a rider, to tip out, to overturn buildings; to slacken the reins, let the hair flow, and stretch out the arms; and in the past participle of troops “spread out loosely”.[2][1] Church Latin glosses it “to pour out, pour forth, shed”.[5] English effuse comes from its participle in the late 14th century.[6]
