Correct spelling, explanation: both gage and gauge are correct spellings, but their usage can depend on context and regional variations. Gage is more commonly associated with specific contexts, such as in the field of measurement, particularly in the context of shotguns. In this context, a gage refers to a standard or a measure. However, it’s less common in general usage and may be considered somewhat archaic. Gauge is the more widely accepted and common spelling in most contexts, especially in American English. Gauge is often used to refer to a standard measurement or an instrument for measuring, checking, or displaying a level, dimension, or quantity.
