Definition:
Let go of an object that is being held.
Required Relationships:
object:
Some tangible entity.
Before this action, the object is
assumed to be held by the agent, i.e. it's in a state of
Be-Held.
Afterwards it's no longer in that state.
agent:
Somebody or something that's holding the object, then lets go of it
Other Common Relationships:
instrument:
the thing (e.g. tool) used to let go of the object
by-means-of:
the event that facilitates letting go of the object
Examples:
John let the dog go.
agent: John
object: the dog
Comment:
It's assumed that John was holding the dog beforehand.
Unobstruct is more general than Let-Go-Of.
Unobstruct allows some object to move more freely, whereas
Let-Go-Of (more specifically) is when an agent stops holding
some object.
