Suffix

This article is about the linguistic term. For other uses, see Suffix (disambiguation).

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 suffixes). An inflectional suffix is sometimes called a desinence.

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.

Suffixes used in English frequently have Greek, French, or Latin origins.

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:

• -s third person singular present
• -ed past tense
• -t past tense
• -ing progressive/continuous
• -en past participle
• -s plural
• -en plural (irregular)
• -er comparative
• -est superlative
• -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:

• -ise/-ize (usually changes nouns into verbs)
• -fy (usually changes nouns into verbs)
• -ly (usually changes adjectives into adverbs)
• -ful (usually changes nouns into adjectives)
• -able/-ible (usually changes verbs into adjectives)
• -hood (usually class-maintaining, with the word class remaining a noun)
• -ess (usually class-maintaining, with the word class remaining a noun)
• -ness (usually changes adjectives into nouns)
• -less (usually changes nouns into adjectives)
• -ism (usually class-maintaining, with the word class remaining a noun)
• -ment (usually changes verbs into nouns)
• -ist (usually class-maintaining, with the word class remaining a noun)
• -al (usually changes nouns into adjectives)
• -ish (usually changes nouns into adjectives/ class-maintaining, with the word class remaining an adjective)
• -tion (usually changes verbs into noun)
• -logy/-ology (usually class-maintaining, with the word class remaining a noun)
