Explanation
Perfectivity concerns how an event is presented aspectually: it is viewed as a whole rather than with its internal unfolding as the main perspective. This differs from telicity, which concerns an inherent endpoint in the event description. A bounded activity without such an endpoint can still receive perfective presentation. Perfectivity, perfect and past tense are likewise not interchangeable. How a language marks viewpoint and what inferences follow must be tested through its constructions. An intuitive external-view metaphor is therefore an aid, not a complete theory of aspectual systems.
Movement of thought
1. Identify the event description. 2. Test for an inherent endpoint. 3. Examine grammatical viewpoint. 4. Record temporal location and perfect constructions separately. 5. Use language-specific readings as countertests.
Scientific use case
Typological research can code telicity, tense and aspect separately and investigate their interaction.
Example
Walking has no inherent destination in itself. A narrative can nevertheless present a bounded walk as a whole event.
Counterexample
A description is not perfective merely because it refers to a past event; past events can also be presented progressively.
Distinction
Distinguish perfectivity from telicity, the perfect, past tense and necessarily achieved goals.
Effect on thought and perception
The distinction separates an event's character from its linguistic presentation.
Resonance
The same happening can appear as a path underfoot or as an outlined stretch.
