A Lovely MondegreenAs indicated below, I am watching the Canadian party leaders' debate, interpreted live into English.
Whoever is interpreting for Elizabeth May caused me to think that in a discussion on gun laws she had a major concern about "semiotic weapons"! My ears perked up. Finally I realized it was "semi-automatic".
There probably are quite a few semiotic weapons being fired in this debate.
"Mondegreen" explanation here.
