It's Merriam-Webster's Word of the Day for April 18th.
Today's word is QUA, spelled Q-U-A.
QUA is a preposition.
It's used in formal speech or writing that means in the capacity or character of someone or something.
It's used synonymously with the word
as to indicate that someone or something is being referred to or thought about in a particular way.

A preposition is a word, and almost always a very small, very common word, that shows direction,
as in to, in a letter to you, location, as in at, in at the door, or time.
as in by in by noon, or that introduces an object as in of in a basket of apples,
or a capacity or role as in as in works as an editor.
As such, prepositions tend not to attract as much attention as other parts of speech,
unless there is some fufferah about whether or not it's okay to end a sentence with one.
