Suffixes may be attached to nouns, adjectives or adverbs. Unaccented vowels should be dropped before adding the suffixes. The most common suffixes are -ito (a) and -cito (a). They express size, affection, admiration, appreciation or pity. The ending -ero (a) indicates the maker or dealer in charge of something. To indicate where something is made or sold, add -ería. When -eza and -ura are added to adjectives, they express abstract nouns. When -dor is added to a verb (minus the final letter), it indicates the performer of the action.
