Subcat: subcategorization
Lexical feature of verbs. Some tagsets distinguish intransitive and transitive verbs. In many languages however, subcategorization of verbs is much more complex than this.
Intr: intransitive verb
A verb that does not take arguments other than the subject.
Examples: [en] to go
Tran: transitive verb
A verb that takes a direct (accusative) object as argument (in addition to the subject). These verbs can be passivized, then the direct object becomes the subject.
Examples: [en] to do something, to be done by somebody
