Ambiguity had had no master
Natural languages evolve without much consideration giving to logical consistency. Really, it's surprisingly that there are not more situations where the language we use corners us into lexical traps. Perhaps as we've grown with a developing language, we subconsciously accept that there is ambiguity in everything we say and that is why communication usually generates and relies on a relationship between deliverer and receiver.
Ambiguity had had no master however, until this gem came to light:
