Words Worth Knowing

Precise words educated adults are expected to know, plus a few that most people use the wrong way.

A good vocabulary is about saying exactly what you mean, not about sounding clever. These are words that come up in books, news and work writing: ubiquitous, pragmatic, cogent, perfunctory. There are also a few traps, such as disinterested, nonplussed and enormity, whose traditional meanings are not the ones most people assume. Each card gives the word; flip it to check the meaning.
