Etymology

Origin of vat

before 1100; Middle English (south); Old English fæt vessel; cognate with Old Norse fat vessel, German Fass keg

Explanation

A vat is a big container for holding liquids. If you're having a big party, your mom may get you to help cook a vat of spaghetti sauce to feed all your hungry relatives. Remember that vat has a short a sound; it rhymes with cat, hat, and sat. Vats are not always food-related. People who make pottery, for example, keep vats of glazes in which they dip their vases and cups in order to color them. No matter what a vat contains, it's often heavy and hard to move.
