An anecdote is a short account of a particular incident or event, especially of an interesting or amusing nature. Anecdotes are usually narrated or shared orally rather than written; sometimes they are offered to lend support to an idea or conclusion based on real-world experience. Unlike the word story, anecdote is not used to talk about the plot of a novel, poem, or drama.

To disclose something is to make it known, or to reveal or uncover it. Unlike the versatile verb tell, which sometimes means simply “to communicate,” disclose is used when the information shared (or as the case may be, not shared) is of a confidential and consequential nature. As you might guess, it’s not used lightly! Under investigation, a corporation might disclose key financial information; upon publishing a high-profile news story, a journalist might refuse to disclose the identify of her source.

The adjective eager suggests desire and enthusiasm tinged with impatience. Keen carries a sense of zest and active, alert desire—one might even call it sharpness. The idea of sharpness slices through all uses of the word keen. A keen razor is a finely sharpened blade. Keen satire is sharp and biting, and a keen mind is one of great acumen or incisiveness. As a synonym for eager, the sharpness of keen turns up as a pointed enthusiasm. To say that you’re not keen on something is an understated way to say that you don’t look forward to that thing, or that you have no enthusiasm for it whatsoever.
