To separate from another. This separation is a characteristic of the entity where absence is presence, and the definition of the element must include the part removed.
To cause an event or moment that changes the direction or meaning of the following time or action. The two are tied in a conditional relationship where one describes or defines the other.
To bear meaning in relation to the observer or an object or time. There is a continuous, formal relationship between the two elements through a discrete or continuous space or time.
To exist near some defined space, time, or limit. The entity is partially or wholly defined by this proximity, and this entity can affect or define the space, et cetera to a lesser extent.
To be close to or created by another. A relationship between the two exists either through proximity or progenitor . The multiple definitions allow new plays on meaning.
To approximate or describe an object or time in relation to another. The two do not need to be related, instead they are two points connected by some commonality.
To be supported by or opposed to another entity. Neither is defined by the other, but a condition is developed in this relationship, and without one or the other, it is impossible to be in this.
To exist on or within an object which is moving through a medium. The element in this state can be foreign to the object but both go to the same place.
To describe an element through the perspective of another. The two objects or times can define each other, but one is minor to the other. The relationship is relative to the frame of reference.
To define an entity through the specific relationship or actions of another. This other may not be described by the entity, however. This is a conditional relationship.
