Which of the following terms refers to words that are formed by putting together two or more words?

The term that refers to words formed by combining two or more individual words is compound words. These are created when two separate words merge to create a new word with its own distinct meaning, such as "notebook" (note + book) or "basketball" (basket + ball). This formation is a fundamental aspect of language, illustrating how new concepts can be expressed through the combination of existing words.

In contrast, antonyms refer to words with opposite meanings, synonyms signify words that share similar meanings, and homographs are words that are spelled the same way but have different meanings or pronunciations. Understanding the concept of compound words is essential in language development and literacy, as it helps young learners decipher and form new vocabulary.
