Categories of text, classified according to the particular purposes they are designed to achieve, which influence the features the texts employ. For example, texts may be imaginative, informative or persuasive; or can belong to more than one category. Text types vary significantly in terms of structure and language features across different languages and cultural contexts. For example, a business letter in French will be more elaborate than a similar text in English; a request or an offer of hospitality will be expressed differently in Japanese or in German.
