Where does the word “Soupcon” come from and What does Soupcon mean?

Coming to us directly from the French, in which it has the same meaning, “a trifle,” the word soupcon has gone through several spellings as the French language itself was evolved.

It stems from the Late Latin suspectio, which comes, in turn, from the Latin suspicio, “a suspicion.”

A soupcon, therefore, is a quantity so small that it may exist only in the imagination.
