X: other
Definition
The tag X is used for words that for some reason cannot be assigned
a real part-of-speech category. It should be used very restrictively.
Cases include:
-
Unintelligible material: For example, gibberish or words that cannot be fully transcribed.
-
Word fragments: This includes truncated words (as in speech) as well as non-initial parts of a goeswith sequence. Depending on a language’s tokenization practices, it may also apply to normally bound affixes that have been split off.
-
Unanalyzed foreign words: Cases of code-switching where it is not possible (or meaningful) to analyze the intervening language grammatically. See the page on Foreign Expressions and Code-Switching. Note that this usage does not extend to ordinary loan words: e.g., in he put on a large sombrero, sombrero is an ordinary NOUN.
X is discouraged for words that clearly belong to the language, even if they are idiosyncratic
in form or distribution and thus do not neatly fit into other syntactic categories.
For example, etc. in English is not an obvious fit for any category, but a regular
category (NOUN) was deemed the closest fit. In other cases, one of the other
non-canonical parts of speech (PART, NUM, SYM, and PUNCT) may be suitable.
