X: other

Definition

The tag X is used for words that for some reason cannot be assigned a real part-of-speech category.

A special usage of X is for cases of code-switching where it is not possible (or meaningful) to analyze the intervening language grammatically (and where the dependency relation foreign is typically used in the syntactic analysis).

Even if foreign words are tagged X, this usage does not extend to ordinary loan words which should be assigned a normal part-of-speech. For example, кілт  “kilt” is an ordinary NOUN.
