Zero (linguistics)
Encyclopedia : Z : ZE : ZER : Zero (linguistics)
A zero, in linguistics, is a constituent needed in an analysis but not realized in speech. It also means a lack of an element as opposed to other elements. It is usually written "Ø".
There are several kind of zeros.
- A zero morph, consisting of no phonetic form, is an allomorph of a morpheme that is otherwise realized in speech. In the phrase two sheep-Ø, the plural marker is a zero morph, which is an allomorph of -s as in two cows.
- A zero affix is a lack of an affix analyzed as another affix. In the phrase I like-Ø it, the verb conjugation has a zero affix, as opposed to the third-person singular present -s in he likes it.
- A zero sometimes works also like a pronoun, as in "nobody knows Ø" and "Ø makes no difference." Likewise, the zero in the book Ø I am reading works like the that in the book that I am reading.
- A zero article is an unrealized definite article in some languages.
