It's easy to overestimate the vocabulary of your target audience, particularly if you yourself are a word person.
So, in that spirit, I'm asking about a word I saw this morning in a marketing promotion: Emissary. "Become an Emissary," read the headline.
Honestly, is this a word you understand at a glance? In your reply, please say whether or not you're a native English speaker.
P.S. Other words I've asked people about included "cheeky" and "obstreperous."
