a battle. Among the most controversial and unsuccessful was Lord Raglan's order at the Charge of the Light Brigade, which being vague and misinterpreted, led to defeat with many casualties. Develop skill/explore ideas Some writers use the writing task to develop their own skill (in writing itself or in another area of knowledge) or explore an idea while they are producing a piece of writing. Philologist J. R. R. Tolkien, for example, created a new language for his fantasy books. Entertain Some genres are a particularly appropriate choice for writers whose chief purpose is to entertain. Among them are limericks, many comics and thrillers. Writers of children's literature seek to entertain children but are also usually mindful of the educative function of their work as well. Influence Anger has motivated many writers, including Martin Luther, angry at religious corruption, who wrote the Ninety-five Theses in 1517, to reform the church, and Émile Zola (1840–1902) who wrote the public letter, J'Accuse in 1898 to bring public attention to government injustice, as a consequence of which he had to flee to England from his native France. Such writers have affected ideas, opinion or policy significantly. Payment Writers may write a particular piece for payment (even if at other times, they write for another reason), such as when they are commissioned to create a new work, transcribe an original one, translate another writer's work, or write for someone who is illiterate or inarticulate.

According to her writer son Anthony Trollope "her books saved the family from ruin". Teach Aristotle, who was tutor to Alexander the Great, wrote to support his teaching. He wrote two treatises for the young prince: "On Monarchy", and "On Colonies" and his dialogues also appear to have been written either "as lecture notes or discussion papers for use in his philosophy school at the Athens Lyceum
