What do we call words like "there" and "their"?

Words like "there" and "their" are called homophones because they sound the same but have different meanings and spellings. Homophones often create confusion in writing and speaking, as they can be easily misused due to their identical pronunciation. In the case of "there," it refers to a place or location, while "their" indicates possession, as in something belonging to them. This distinction is crucial in understanding both spoken and written English.

The other choices, such as synonyms and antonyms, refer to words that have either similar meanings or opposite meanings, respectively, rather than focusing on pronunciation. Homographs pertain to words that are spelled the same but may have different meanings and pronunciations, which does not apply to "there" and "their."
