61 words the Digital SAT draws on when a passage turns to activity and inactivity — each with its part of speech, a plain-English definition, and an example sentence showing how it behaves in context.
Vocabulary on the Digital SAT is tested in context, not in isolation: a Words in Context question hands you a sentence with a blank and four plausible-looking candidates, and the winner is the one whose shade of meaning fits. Studying words in a meaning-group like this one is the fastest way to build that discrimination — you learn activity and inactivity as a spectrum rather than as 61 unrelated definitions.
Read the definition, then the example sentence. Say the word aloud. Come back to this theme a few days later and cover the definitions — recalling a word cold is what fixes it, and rereading it is not.
