The document discusses word stress in English pronunciation. It explains that in English, one syllable within a word is accented louder than the other syllables. It provides some rules for where stress is typically placed in two-syllable words like nouns, verbs, and adjectives. However, it notes there are many exceptions. Examples are given to illustrate how stress changes the meaning of words like "present" and "contract". The document encourages learners to feel the natural stress of words rather than rely solely on rules.
