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 foreign is typically used in the syntactic analysis). 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 Он надел килт  “He put on kilt”, килт is an ordinary NOUN.


X in other languages: [bej] [cs] [cy] [da] [el] [en] [es] [ess] [et] [fi] [fr] [ga] [grc] [hy] [it] [ja] [ka] [kpv] [ky] [myv] [no] [qpm] [ru] [sl] [sv] [tr] [tt] [uk] [u] [urj] [xcl] [yue] [zh]
