The symbol (Unicode U+2061) is called “FUNCTION APPLICATION.” It represents function application in notation: placing it between expressions signals that one part is applied to another, similar to reading it as “applied to.” It is used most often in typeset, mathematical, logic, and programming-adjacent contexts where clarity matters and the author wants a compact, typographically correct separator. Because it’s a specific Unicode punctuation character, copying and pasting it directly is the easiest way to preserve the intended meaning across documents and websites.
