Intonation describes how the voice rises and falls in speech. Rising intonation is used for yes/no questions and clarifying ideas, while falling intonation is used for statements and WH-questions. Stress refers to emphasis placed on a particular syllable or word, usually increasing volume, pitch, or length. Word stress follows patterns based on the type of word such as compound words, verb-adverb combinations, and adjective-noun pairs. Tag questions turn statements into questions by adding a short question after, used to check understood information. Decoding word meaning involves identifying the root word and any prefixes or suffixes.
