We won’t leave you guessing about today’s word: the verb conjecture means “to conclude or suppose from grounds or evidence insufficient to ensure reliability.” If you guess what’s going to happen, you may be risking an opinion on something about which you know nothing or very little. If you conjecture an outcome, you are drawing conclusions based on available information, with the understanding that the information is partial. While neither of these terms deals in certainty, the latter suggests a more reasoned approach to determining what's probable.

The adjective audacious takes boldness to the extreme—and sometimes that’s a good thing. When used to describe an idea, goal, or plan, audacious usually suggests inventiveness and originality. But sometimes audacious is used to suggest brazen insolence and reckless defiance of convention, property, or law. An audacious lie, for instance, is an egregious and insidious falsehood delivered without shame.

Trick or treat—today's synonym is pretty sweet! The noun treat is used to refer to anything that affords particular pleasure or enjoyment. On Halloween, treat, of course, means candy! After accumulating a sufficient amount of treats, a pint-sized caped crusader or ferocious jungle cat might spend some time admiring their goodies. The word goody (also spelled goodie) is almost always used in the plural to refer to things especially tasty or pleasing. Something that stands the test of time, as classic song or TV episode, might be called an oldie but a goodie, and a bag of gifts given to guests at an event or party is a goody (or goodie) bag.
