I cannot agree with you. Which of the 430 meanings of the word “set” listed in the Second Edition of the Oxford English Dictionary is the “correct” one?

[Bernard Marx]

I think context goes a long way toward defining the specificity of a given word usage. I haven't looked up all 430 definitions of "set" in the OEM but, in context, I suspect the varied meanings become clear. To use your example a trapper friend "sets" traps (verb). But once in place they're called "sets" (noun).
