Syllogistic validity requires each term keep one consistent sense

Evidence

Categorical syllogism Rule One not only insists that the argument contain exactly three terms, but that each term be used in the same sense throughout the argument. When different senses are utilized, linguistic fallacies occur. Some of these are fallacies of ambiguity (equivocation and amphibology). Others are known as fallacies of composition, division and vicious abstraction. — Ruggero J. Aldisert, Agatha D. Aldisert, Logic for Lawyers- A Guide to Clear…, 1193
