You are correct, but in Forth for example, the colon is a word in the dictionary of words and so is semi-colon. They just happen to parse the input stream rather than taking arguments off the stack. Everything in Forth is called a "word".

So depending who your lawyer is, : and ; are "words". :=)

I am not generally knowledgeable about Forth and languages like it because the only experience I have writing in anything close to forth is in my own language. Thanks for explaining.

Yes. In forth some words have the "immediate" flag set. When such words are encountered during compilation they are executed nevertheless. This allows words such as ; to end a word definition and return to interpretation mode.
