Prototype Meaning
The prototype meaning of penis is the external male reproductive organ found in human males and other male mammals. When most people hear this word, they think of the complete anatomical organ rather than a particular part, such as the shaft or glans. It has two important biological functions: allowing urine to leave the body and helping deliver semen during sexual reproduction. This basic meaning is the foundation for understanding its medical terms, euphemisms, and informal alternatives.

Understanding these differences improves vocabulary, makes writing more natural, and helps English learners avoid awkward word choices.
