Asterism

A thousand words worth knowing

Coming to iPhone canny grok shrewd sagacious perspicacious

An asterism is a small pattern of stars, like the Big Dipper. Here, every word is a star. Learn a family of related words and it lights up as an asterism.

“I collected these words over a decade from books, conversations, articles, podcasts and friends. This game is how I finally learned them.” —JM

How it works

Asterism is built on well-established research into how memory works. See the studies

  • You answer. You don't just read.

    Every time you meet a word, it's a question. Pulling a word out of your own memory is what makes it stay.

  • Words come back at the right time.

    Get one right and it returns in a day, then three days, then a week, then months. Spread-out practice lasts. Cramming doesn't.

  • Words travel in families.

    Related words are grouped so you see how they differ and how they connect, the way an asterism joins its stars.

  • Learn it well enough to use it.

    Recognizing a word isn't the goal. A word counts as yours once you can supply it yourself, in a real sentence.
