Explanation
The use of existing linguistic material for a new function after its original motivation has disappeared. An apparent remnant can re-enter the system as a resource.
Example
An old inflectional opposition later takes on a new grammatical function.
Counterexample
The regular continuation of the same function is not exaptation.
Distinction
Distinguishing from grammaticalization: The regular continuation of the same function is not exaptation.
Effect on thought and perception
An apparent remnant can re-enter the system as a resource.
Resonance
Exaptation makes a directed relationship perceptible: An apparent remnant can re-enter the system as a resource.
