Do four or five minute lists.* Make your own categories, or use these: words with dis-, il- or anti- as a prefix, names for next year’s popular shades of paint, words pertaining to hardware, words beginning with the letter G, onomatopoetic words for wilderness sounds.
* MINUTE LISTS are a language brain warmup. For each list item, set the timer for one minute and write as many words as you can think of in that item’s category. Write at speed and take anything that comes to mind, even if the words popping up are incorrect matches or not real words. The speed and free-for-all ethos are aimed at getting your vocabulary moving.
