前後屬詞素

维基百科，自由的百科全书

In 语言学, a 前後屬詞素(clitic) is a 词语 that 句法 functions as a 自由詞素, but phonetically appears as a 規範詞素; it is always pronounced with a following or preceding word. A clitic is either an enclitic, where the clitic is with the preceding word, or a proclitic, which is with the following word. Some languages, like 葡萄牙語, also have mesoclitics, which are inserted in the middle of the word.

A word and a clitic attached to it are pronounced like a single word, which respects the usual rules of the 语言 in question. For example, if a word must have one and only one stressed syllable, then a word with a clitic must too (the clitic is usually unstressed). Clitics are often written as separate words.

A clitic is not an affix. An affix syntactically and phonologically attaches to a base morpheme of a limited part of speech such as a verb, to form a new word. A clitic syntactically functions above the word level (i.e. on the phrase or clause level) and attaches only phonetically to the first, last, or only word in the phrase or clause, whichever part of speech the word belongs to.

In the 印歐語系, some clitics can be traced back to 原始印歐語: for example, -k^we is the original form of Latin -que, Greek te, and Sanskrit -ca. This word means "and" and is said after the word being added, e.g. 元老院與羅馬人民 "Senate and People of Rome".

The English enclitics are:

The abbreviated forms of be:
- 'm in I'm
- 're in you're
- 's in she's
For negation, the abbreviated form of not:
- n't in couldn't
  - this abbreviated form of not has been proven to be an affix rather than a clitic (Zwicky & Pullum, 1983).
The abbreviated forms of auxiliary verbs:
- 'll in they'll
- 've in they've
To express the possessive of a phrase:
- 's in the girl next door's cat

(It's not just the door's cat.)

And the English proclitics are:

a in a desk
an in an egg
the in the house

In the Romance languages, the articles and the non-emphatic object pronouns are all clitics. In Spanish, for example:

las aguas ("the waters") = /la'saguas/

lo hicimos ("we made it") = /loi'simos/

dámelo ("give it to me") = /'damelo/

Clitics in other languages:

Latin: que and, ve or, ne (yes-no question)
Greek: te and, de but, gar for (in a logical argument), oun therefore
Russian: ли (yes-no question), же (emphasis), не not (proclitic), бы (subjunctive)
Japanese: all particles, such as the genitive postposition の no and the topic marker は wa
Dutch: 't definite article of neuter nouns and third person pronoun, 'k first person pronoun, je second person pronoun, -ie third person pronoun (this one should not be written as a separate word, i.e "Doet-ie 't nog?": "Is it still working?"; lit. "Does it still do it?")
