X: other


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:

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.


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]
