X: other


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 flat is typically used in the syntactic analysis; on the morphological layer, these words should use the feature Foreign=Yes). This rarely applies to the PDT data where many foreign words are tagged with their original part of speech.

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, in Skotové nosí kilt  “Scots wear kilts”, kilt is an ordinary NOUN.
