Etymology
The English word "penis" has a clear and direct history that traces back to Latin, the language of ancient Rome.
Ancient Root: The word comes directly from the Latin noun pēnis.
Original Meaning: In Latin, the word pēnis originally meant "tail." Think of it as a descriptive term for an appendage or a hanging part. The anatomical meaning—referring to the male organ—was a metaphorical extension, or a secondary meaning, that came from this initial sense of "tail."
Adoption into English: The word was formally borrowed into English from Latin, primarily by medical and scientific writers, beginning around the late 16th century (with some sources citing its use as early as 1578, and becoming more common in the mid-to-late 17th century).
Why it was Adopted: Before "penis" became common, English speakers often used Old English words like "yard" or "pintle," or various crude slang terms. The Latin term "pēnis" was adopted specifically for its clinical and formal neutrality, allowing for discussion of the organ in medical or polite contexts without using vulgar language. Therefore, its first known use and meaning in English were exactly what they are today: the male organ of copulation and urination.
In short, the anatomical term you use today is a formal, scientific borrowing from Latin, where it simply meant "tail."
