This document discusses complex word stress in English. It covers several types of complex words formed from affixes or compounds. For words with affixes, the affix may receive primary stress, stress remains on the stem, or stress shifts within the stem. Common suffixes are discussed, some carry their own stress while others do not affect stress placement. Prefixes do not regularly carry or shift stress in predictable ways. Compound words may be stressed on the first or second element depending on the word class. Variable stress can occur in connected speech or between dialects. Word-class pairs with identical spelling but different stress include noun/verb pairs where the verb is stressed on the second syllable and the noun/adjective on the first.
