Quandary is a noun that refers to a situation featuring a difficult choice. 

It’s not clear where exactly our word of the day came from, but it may have emerged from the Latin word quando (KWAN doe) which means ‘when.’ Quandary is a synonym for dilemma, but our word of the day is more likely to be used in formal settings. Here’s an example:

The judge ruled that the defendant was not at fault when faced with a quandary. The choice may have been a tough one, but he did the right thing.
