Did you know?

When it comes to bigness, there’s grand and then there’s grandiose. Both words can be used to describe something impressive in size, scope, or effect, but while grand may lend its noun a bit of dignity (i.e., “we had a grand time”), grandiose often implies a whiff of pretension. The difference between a grand plan for the city park and a grandiose one, for example, might be the difference between a tasteful fountain and a garden full of topiaries cut in the shapes of 19th century literary figures. So if you’re choosing between the two, a helpful mnemonic might be that the extra letters in grandiose suggest that one’s ideas, claims, promises, schemes, dreams—you get the idea—are a bit extra.
