The arrangement of identifiable repeated or corresponding elements in a text. These include patterns of repetition or similarity (for example, the repeated use of verbs at the beginning of each step in a recipe, or the repetition of a chorus after each verse in a song). The patterns may alternate (for example, the call and response pattern of some games, or the to and fro of a dialogue). Other patterns may contrast (for example, opposing viewpoints in a discussion, or contrasting patterns of imagery in a poem). The language patterns of a text contribute to the distinctive nature of its overall organisation and shape its meaning.
