Minutia

Proper Spelling and meaning: Minutia is a singular noun meaning a small detail. Minutiae is the Latin plural of minutia, and we usually use it in English. Latin plurals are often tricky, and many eventually drop out of English in favor of –s plurals, but minutiae is deeply entrenched and is likely to stick around, at least in more formal and technical writing registers. Minutias does not regularly appear.

But minutia is often treated as a mass noun (e.g., all the minutia is slowing us down), and it’s sometimes treated as plural, as in the first three examples below. If either of these usages becomes more common, we could soon see minutiae begin to fade from popular usage.
Examples

Because we usually speak of trivial details as plural rather than singular, minutia should properly be less common than minutiae. But minutia is often used in place of its plural—for example:

Menusha
An idiot trying to spell minutia.
While it may seem to be minutia, anyone who writes menusha is a f-ing dumbass.
