Questão 3167842

Prefixation in English, as in "unhappy" and "disagree," is exclusively used to create words with positive meanings.

Suffixation is a process that only changes the grammatical class of a word, without affecting its basic meaning, as in "joy" (noun) to "joyful" (adjective).

In English, suffixes do not have semantic functions and are used only to determine the pronunciation of complex words.

Words formed by compounding, such as "breakfast" and "sunflower," cannot be used in formal contexts due to the informal nature of these combinations.

Derivation involves adding affixes (prefixes or suffixes) to a base, while compounding creates new words by combining two independent bases, as in "notebook."
