IPA: /θaɪˈʊəriə/
KK: /θaɪˈʊəriə/
A white crystalline substance used in photography and organic chemistry, similar to urea.
Thiourea is often used in the development of photographs.
Thiourea is formed from "thio-" (from Greek "thio", meaning sulfur) and "urea" (from Latin "urea", meaning urine or a compound derived from urine). The word refers to a compound that contains sulfur and is related to urea, which is a product of protein metabolism.
Think of 'thio-' meaning sulfur and 'urea' relating to urine — thiourea is a compound that combines sulfur with a substance found in urine.
