A setting which lets you restrict a word list to words with neighbouring tags such as <ADJECTIVE>cheerful. Only applies if you have loaded up a tag file.
In this listing, OF is visible but untagged.
This word list, however, only consists of items with a tag matching those in the tag file (of verb tags) used with data derived from the BNC XML edition.
Notice that SEE and KNOW appear twice, distinguishing infinitive and base forms.
