A verbal marker is a resultative marker if it signals that the situation denotes a state resulting from the past event denoted by the verb root.
According to Nedjalkov's (1988) definition, the subject of a resultative verb must be its patient argument, but this is not included in the definition here.
"Resultatives signal that a state exists as a result of a past action. The resultative is often similar to the passive in that it usually makes the patient the subject of the clause but differs in that a resultative may apply intransitive verb, as in He is gone, without a change of subject. Resultatives are compatible with the adverb 'still' and are used only with telic verbs, that is, verbs which describe events which have inherent endpoints." (Bybee et al. 1994: 54)
