In linguistics, a grammatical agent is the cause or initiator of an event. The word agent is also used in this manner in Hilinqwo. Note that the agent is not necessarily the subject of the sentence. Consider the two sentences:

Kanos edit karnom. Dogs eat meat.
Karnos edtit kanom. Meat is eaten by dogs.

In both statements, kan* ("dog") is the agent. Karn* ("meat") is the patient. The voice used reflects the direction of agency. The first sentence is of the active voice: The subject is the agent and the direct object is the patient. The second sentence uses the passive voice: The subject is the patient and the direct object is the agent.

Hilinqwo also recognizes the following aspects of agency:

Instrument The means by which the indicated action or situation takes place. Usually something discrete and tangible. dis tg
Intent The ends of the action or situation. dis itg
Result The tangible product or result of the indicated action or situation. tg
Facility The location where the indicated action or situation takes place. dis tg
The reason for the action. dis itg

The groups of the Agency supergroup are mutually exclusive.
