The word "deterged" is rarely used in modern English, but it means "cleansed thoroughly" or "purified." It is spelled with a "d" followed by the letters "e," "t," "e," "r," and "g," then ending with "ed." The IPA phonetic transcription of this word is [dɪˈtɜrdʒd], where the "d" sound is pronounced like the letter "d," the "ɪ" sounds like the "i" in "sit," the "ˈ" indicates stress on the second syllable, and the "dʒ" sounds like the "j" in "jacket."
The word "deterged" is a verb derived from the Latin word "detergere", which means to cleanse or wipe off. The Latin word is a combination of "de-" (meaning "down" or "off") and "tergere" (meaning "to wipe"). Over time, the word "deterged" entered the English language through Latin and retained its meaning of cleaning or cleansing.
