In William Boyd’s new novel Sweet Caress, the characters make up a game to pass the time in their work as society photographers. You have to describe the people you meet in four adjectives, to the agreement of all players.
This game can be turned into a useful way of looking at character in literature or history. So, for example, Henry the Eighth was fat, talented, paranoid and murderous; Macbeth initially appears as a brave, loving, loyal and suggestible man.
This works well for exam preparation and revision, where precise language saves time. I expect you could use it in almost every subject. The discussion of which four words to select is an interesting way to begin a lesson.
