A paronym is a word that has a close relationship to another word, either through sound or meaning. There are several other terms that can also be used to refer to paronyms, including homonym, heteronym, homophone, and homograph. Homonyms are words that sound the same but have different meanings, while heteronyms are words that are spelled differently but sound the same. Homophones are words that sound the same but may or may not be spelled the same, while homographs are words that are spelled the same but have different meanings. These terms can be confusing, but understanding the difference between them can help to improve your language skills.
