Word formation is a central topic in linguistics, particularly within the field of morphology. It refers to the mechanisms through which new words are created or existing words are modified in a language. These processes play a crucial role in language evolution, lexical expansion, and communicative efficiency. English, as a dynamic and flexible language, presents a variety of word formation strategies. Judge the sentences below as TRUE (T) or FALSE (F).

For example, the addition of the prefix un- in unhappy changes the meaning, while the suffix -ness in happiness transforms an adjective into a noun. Derivation is highly productive and contributes significantly to vocabulary growth.
