There are three types of stress related to words. These are primary, secondary, and weak stress. Primary stress denotes the strongest syllable of a word, secondary denotes strong syllables with less emphasis than the primary, and weak syllables are typically realized by the schwa. In English can also be used to differentiate homographs such as object vs. Object. Stress contributes to the rhythm of a language with languages being either stress times (English, Dutch) or syllable times (Italian, Spanish).
