Etymology: Before it described instruments, the word named a tax official. A gauger was an officer who measured the contents of casks and barrels so that duty could be charged on what they held. The sense of measuring a container's capacity came first, and the broader sense of measuring any quantity grew out of it. The word comes from Old French "jauger," to measure, which is related to "jauge," a measuring rod or gauge. Its ultimate origin is uncertain, and proposed Latin sources remain unconfirmed. "Guager" is an older spelling variant of "gauger," with the initial sound written "gu" as in French, and it survives mainly in older texts.

Synonyms: measurer, inspector, evaluator, meter reader, assessor
