To gauge is to measure or estimate — gauge the depth, gauge the mood. To gouge is to scoop or cut out roughly, and figuratively to overcharge: price gouging. Measuring takes the AU; scooping takes the OU.
The core difference
Measuring and scooping.
- gauge — measure or judge: a pressure gauge, gauge reaction. Also thickness: 16-gauge wire.
- gouge — scoop out; overcharge: gouged a channel, price gouging.
The spelling
Gauge is one of the more frequently misspelled words in English — "guage" appears constantly, because the AU order feels wrong. There is no rule to lean on; it simply has to be learned, though remembering that it shares its opening with gauze and gaunt helps a little.
The gauge senses
Beyond measuring, gauge names a standard of thickness or size — wire gauge, shotgun gauge, railway gauge. All from the measuring idea.
Frequently asked questions
Which spelling means to measure?
Gauge, with AU.
What is price gouging?
Charging excessively, especially exploiting a shortage — from the scooping-out sense of gouge.
Why is gauge so often misspelled?
The AU order feels counterintuitive, so "guage" is a very common error. There is no rule — it has to be learned.
