turd: [OE] Turd is an ancient word, traceable right back to Indo-European *drtom. This was formed from the base *dr-, *der- ‘flay, tear’ (source also of English tear), and so etymologically denoted that which is ‘separated’ from the body, like flayed skin, and hence ejected or excreted from the body. It passed into English via prehistoric Germanic *turdam. A distant relative is Latvian dirsti ‘defecate’.

turd (n.)youdaoicibaDictYouDict
Old English tord "piece of excrement," from Proto-Germanic *turdam (cognates: Middle Dutch torde "piece of excrement," Old Norse tord-yfill, Dutch tort-wevel "dung beetle"), from PIE *drtom, past participle of root *der- (2) "to split, peel, flay, tear;" thus "that which is separated ("torn off") from the body" (compare shit (v.) from root meaning "to split;" Greek skatos from root meaning "to cut off; see scatology). As a type of something worthless and vile, it is attested from mid-13c. Meaning "despicable person" is recorded from mid-15c.
