Usage

What does ur- mean? Ur- is a combining form used like a prefix that has two unrelated senses.The first is “urine.” It is used occasionally in medical terms, especially in pathology. In some rare instances, like urate, ur- specifically denotes uric acid, a compound found in urine. This ur- comes from Greek oûron, meaning “urine.” Other combining forms that mean "urine," such as urino- and urin-, come from the Latin for "urine," ūrīn(a).The second is “earliest” or “original.” It is frequently used or appendaged to a wide variety of terms. In some instances, it is stylized with a hyphen after the form, as in ur-fascism. Because the German language capitalizes nouns, the combining form ur- sometimes appears as Ur-, as in Urheimat. This ur- comes from Old High German ur-, meaning “thoroughly.”Despite popular misconception, the name Uranus, a planet named for a Roman god, does not use the combining form ur- to mean "urine” or “earliest.” Discover more about the origins of this name at our entry for Uranus. The chemical compound uranium is also named after this figure from Greco-Roman mythology.What are variants of ur-?The “urine” sense of ur- are variants of uro-, which loses its -o- when combined with words or word elements beginning with vowels.

This uro- ultimately comes from Greek ourá, meaning “tail.”
