Words That Use ur-
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.
