In linguistics, a suffix (also sometimes termed postfix or ending) is an affix which is placed after the stem of a word. Common examples are case endings, which indicate the grammatical case of nouns or adjectives, and verb endings, which form the conjugation of verbs. Particularly in the study of Semitic languages, a suffix is called an afformative, as they can alter the form of the words. In Indo-European studies, a distinction is made between suffixes and endings (see Proto-Indo-European root). A word-final segment that is somewhere between a free morpheme and a bound morpheme is known as a suffixoid or a semi-suffix (e.g. English -like or German -freundlich 'friendly'). Suffixes can carry grammatical information (inflectional suffixes) or lexical information (derivational/lexical suffixes). An inflectional suffix is sometimes called a desinence or a grammatical suffix. Some examples in European languages: Girls, where the suffix -s marks the plural.He makes, where suffix -s marks the third person singular present tense.It closed, where the suffix -ed marks the past tense.De beaux jours, where the suffix -x marks the plural.Elle est passablement jolie, where the suffix -e marks the feminine form of the adjective. Many synthetic languages—Czech, German, Finnish, Latin, Hungarian, Russian, Turkish, etc.—use a large number of endings. Inflection changes the grammatical properties of a word within its syntactic category.In the example: I was hoping the cloth wouldn't fade, but it has faded quite a bit. the suffix -ed inflects the root-word fade to indicate past tense. Inflectional suffixes do not change the word class of the word after inflection.Inflectional suffixes in modern English include: \n* -s third person singular present \n* -ed past tense \n* -t past tense \n* -ing progressive/continuous \n* -en past participle \n* -s plural \n* -en plural (irregular) \n* -er comparative \n* -est superlative \n* -n't negative Derivational suffixes can be divided into two categories, namely class-changing derivation and class-maintaining derivation.Derivational suffixes in modern English include: \n* -ise/-ize (usually changes nouns into verbs) \n* -fy (usually changes nouns into verbs) \n* -ly (usually changes adjectives into adverbs) \n* -ful (usually changes nouns into adjectives) \n* -able/-ible (usually changes verbs into adjectives) \n* -hood (usually class-maintaining, with the word class remaining a noun) \n* -ess (usually class-maintaining, with the word class remaining a noun) \n* -ness (usually changes adjectives into nouns) \n* -less (usually changes nouns into adjectives) \n* -ism (usually class-maintaining, with the word class remaining a noun) \n* -ment (usually changes verbs into nouns) \n* -ist (usually class-maintaining, with the word class remaining a noun) \n* -al (usually changes nouns into adjectives) \n* -ish (usually changes nouns into adjectives/ class-maintaining, with the word class remaining an adjective) \n* -tion (usually changes verbs into noun) \n* -logy/-ology (usually class-maintaining, with the word class remaining a noun)
