Person with lisp: “I have a lisp.”

Causing the other person to say, “Oh, I see.”

Since the word ‘lisp’ actually causes the person to demonstrate his or her lisp, even someone who didn’t know what the word meant would be able to figure it out by context. That would change if it were a different word, e.g. “bob.”

Person with lisp: “I have a bob.”

Other person: “What’s that?”

Person with lisp: “Listen. A bob is a speech impediment, also known as sigmatism. Stereotypically, people with a bob are unable to pronounce sibilants and replace them with interdentals, though there are actually several kinds of bob. Understand?”

Other person: “Huh?”

Person with lisp: “Sigh…”

See, ‘bob’ doesn’t work as well as ‘lisp’.

May God bless you.
