    Example

    The doctor explained how the penis and other parts of the male body work.

    Example

    In placental mammals, the penis serves a dual function as both a reproductive organ and a channel for the excretion of urine from the bladder.

    Usage

    In medical and scientific contexts, this is the standard, neutral term; in social contexts, it is often avoided in favour of euphemisms or more clinical language depending on the setting.

    Teacher's tip

    While this is the correct anatomical term, it can feel overly clinical or sensitive in casual conversation. Students should be aware that it is the appropriate word for biology or healthcare contexts.

    • phallus
Origin

From late 17th century. Learned borrowing from Latin pēnis (“tail, penis”), from Proto-Indo-European *pes- (“penis”). Displaced native English pintle, tarse, pillicock.
