The document discusses rules of thumb for word stress in English. It explains that stress is louder volume and longer vowel sounds on certain syllables that can change a word's meaning. For two-syllable words, stress is usually on the first syllable whether it is a noun or adjective. Three-syllable words usually stress the first. Compound nouns stress the first part, while compound adjectives and verbs stress the second part. There are also rules for words ending in suffixes like -ic, -tion, -cy, and -al, which typically stress the syllable before the last one or two.
