This lesson explains homonyms, homophones, and homographs, which are groups of words that can have the same sounds or spellings but different meanings. Homonyms are words with the same spelling and pronunciation but different meanings, such as “bat” (animal/sports equipment) or “tie” (clothing/game score). Homophones sound the same but have different spellings and meanings, like “piece/peace” and “sun/son.” Homographs are words spelled the same but with different meanings and sometimes different pronunciations, such as “lead” (to guide/metal) or “tear” (rip/cry). Students practice identifying and using these words through worksheets, quizzes, and assessment tests to improve vocabulary and understanding of English word usage.
