slashed-O (Ø, ø):
zero, nothing.
(Typographically, a letter O with a slash [3].
The upper-case (Ø)
and lower-case (ø)
forms are often used interchangeably,
whichever looks best in a particular context.
The symbol presumably originated as
a typographical substitute for the null sign
of symbolic logic (
),
and sometimes that symbol is still used instead of the slashed-O.)
The symbol has several distinct uses in linguistics.
slashed-O (Ø) [1]:
a symbol which is used in descriptions of linguistic changes,
especially phonological ones,
to indicate a deletion or an
epenthesis (insertion).
For example,
i
Ø
means that i is deleted,
and Ø
i
means that i is inserted.
[Spanish:
O con diagonal [1]]
slashed-O (Ø, ø) [2]: a symbol which is used, when dividing a word into morphemes, to indicate a zero morpheme. For example, in Nahuatl the verb "nemiskeh" 'they will walk' can be divided "ø-nemi-s-keh" (they-walk-future-plural). [Spanish: O con diagonal [2]]
