Concept:Word formation refers to creating new words by combining existing words or adding prefixes and suffixes to root words.
Explanation:Word formation mainly works through two processes: compounding and affixing.
Compounding joins two separate words to form a new word with a distinct meaning, like ‘earthquake’ from ‘earth’ and ‘quake’.
Affixing adds a prefix or suffix to a base word to change its meaning or grammatical form, such as adding ‘-ly’ to ‘quick’ to make ‘quickly’.
Other options like opposites, meaning, verbs, nouns, synonyms, or euphemisms describe word relationships or usage, not the process of forming new words.
Only compounding and affixes are the core methods of word formation in English.
