"SEMS" is an abbreviation for "scanning electron microscope", so it may not be necessarily wrong. But it will be the majority of the time...

Any (or almost any) typo could be seen as a valid abbreviation.

Don't worry, any typo could be a name (of a person, of a place, of a fictive character or place). We wouldn't have a dictionary of possible typos if we were to take that into account.

I can remember @peternewman writing something similar in the past but can't find that anymore. There it was IIRC suggested that if a project is using such an abbreviation it could be excluded on a case by case via the relevant exclude / ignore functionality of codespell.

@larsoner Could you merge this? Again a codecov error as far as I can see.
