urine
UK: ˈjʊərɪn | US: ˈjʊrɪn
n. a liquid by-product of metabolism in the bodies of many animals, including humans, excreted through the urethra.
The word "urine" traces back to Latin urina, which originally referred to liquid waste but also carried connotations of "rain" or "moisture" in its Proto-Indo-European root (h₁wers-). This reflects an ancient metaphorical link between bodily fluids and natural water cycles. Over time, the term narrowed to its specific biological meaning in English.
