Compounding is the process of combining two or more words to make a new word, while decompounding is the opposite process; breaking a compound word into its individual components. Some antonyms for decompounding include compounding, joining, merging, and combining. Instead of separating words, these antonyms involve the creation of new words by joining existing ones. Other antonyms for decompounding include synthesis, aggregation, amalgamation, and integration, all of which translate to the act of putting different things together in one whole. While decompounding is useful in identifying the meanings of complex words, compounding and its antonyms are essential tools for creating new words in everyday language.
