Usage
What does vas- mean? Vas- is a combining form used like a prefix meaning “vessel,” typically referring to blood vessels, such as veins and arteries. It is often used in medical terms, especially in anatomy. In some instances, vas- specifically refers to the vas deferens, the duct that carries sperm to the penis. Vas- is a variant of vaso-, which loses its -o- when combined with words or word elements beginning with vowels. Want to know more? Read our Words That Use vaso- article. Vas- comes from the Latin vās, meaning “vessel.” The Latin vās is also the source of the word vase, which is, after all, a type of vessel—often for flowers! And the diminutive form of vās is vāsculum, literally “little vessel”; it’s the source of the word vascular, commonly encountered in cardiovascular.
