X: other

The English tag X is used for the PTB tags FW, LS, XX, ADD, AFX, and GW. Some things tagged AFX would be candidates for retagging with other tags, but that has not been attempted.


Treebank Statistics (UD_English)

There are 655 X lemmas (3%), 657 X types (3%) and 1139 X tokens (0%). Out of 17 observed tags, the rank of X is: 7 in number of lemmas, 7 in number of types and 15 in number of tokens.
