Homonyms are words that sound the same but have different meanings and spellings.
* Read (present tense): To look at and understand written words. (e.g., "I read the newspaper every morning.")
* Read (past tense): To have looked at and understood written words. (e.g., "I read the book yesterday.")
They have the same pronunciation and spelling, but they represent different tenses of the same verb. This is a case of homography, where words have the same spelling but different meanings and often different pronunciations.
