Etymology
The word "urethra" is a direct borrowing from Late Latin, which itself originated from the Greek ourēthra. This Greek term was a compound of ouron (urine) and -ēthra, a suffix denoting a channel or passage. The literal Greek construction, "a channel for urine," perfectly describes the anatomical function. The term entered English in the late 16th century via medical Latin, retaining its precise, descriptive meaning from its classical roots without significant semantic shift.
Analysis
"ure" is from greek ouron, meaning "urine". "thra" is a simplified representation of the greek suffix -ēthra, meaning "channel" or "passage", derived from the greek ēthra (a place for, a channel).
