What does vae mean?
Vae is a rare English word with two quite different uses. In anatomical terminology, it is the plural of va, a term for a vein, especially a small vein. It therefore refers collectively to such veins, much as the Latin vena has the plural venae. Vae is not normally used in contemporary clinical prose, but it appears in older medical glossaries and anatomical descriptions. The word also exists as a Latin-derived exclamation of sorrow: “woe” or “alas.” Its celebrated use is in the Latin phrase vae victis, meaning “woe to the vanquished.” The interjection is encountered mainly when writers quote Latin sayings or discuss Roman culture; it is not an ordinary English interjection in casual speech. Although vae looks unfamiliar, it illustrates how specialized vocabulary and borrowed classical expressions can preserve one spelling for unrelated functions. Recognising both senses prevents a medical plural from being mistaken for a lament, while understanding vae victis makes an old Latin phrase immediately intelligible.

An exclamation of sorrow meaning “woe” or “alas,” particularly familiar from the Latin phrase vae victis.
