Questions: Aktionsart (Lexical Aspect)

Question 1

A student classifies 'run' as an accomplishment because running takes time and can last an hour. What error have they made?

• A. 'Run' is a state, not an accomplishment, because it lacks internal dynamism
• B. 'Run' is an activity — it is dynamic and durative but lacks a telic endpoint; 'run a marathon' is an accomplishment
• C. Duration alone is sufficient to classify a predicate as an accomplishment; the student is correct
• D. 'Run' is an achievement because it describes a rapid physical transition

Answer: (B)

Accomplishments require both durativity AND telicity — they have a built-in natural endpoint. 'Run' alone has no inherent completion point: you can run indefinitely without reaching any goal. It passes the atelic diagnostic: 'She ran for an hour' is perfectly natural, but 'She ran in an hour' is odd or requires special context. Add a goal ('run a marathon,' 'run to the store') and the predicate becomes telic — now 'in two hours' is natural and the event can be completed or left incomplete.

Question 2

Which diagnostic best distinguishes accomplishments from activities?

• A. The progressive test — activities accept the progressive freely; accomplishments do not
• B. The 'for an hour / in an hour' test — accomplishments accept 'in an hour' naturally; activities accept 'for an hour' but resist 'in an hour'
• C. The stative test — accomplishments resist the progressive; activities are fully compatible with it
• D. The perfect entailment test — activities entail completion in the perfect; accomplishments leave completion open

Answer: (B)

Telicity is what distinguishes accomplishments (telic) from activities (atelic), and the 'in an hour / for an hour' test probes exactly this. 'She built the bridge in a year' is natural; 'She built the bridge for a year' implies she didn't finish. 'She swam for an hour' is natural; 'She swam in an hour' is odd without a telic modifier. Both classes accept the progressive and do not resist it, so the progressive test (option A) doesn't help here — it distinguishes states (which resist progressive) from dynamic predicates.

Question 3

Grammatical aspect (e.g., the English progressive or perfect) and lexical aspect (Aktionsart) are two names for the same phenomenon, differing primarily in whether they are studied by linguists or philosophers of language.

• T. True
• F. False

Answer: False

They are analytically distinct. Aktionsart (lexical aspect) is an inherent property of the verb or predicate phrase — the temporal structure built into its meaning. Grammatical aspect is what the speaker imposes through morphosyntactic marking (progressive, perfect, etc.) — it reflects the speaker's perspective on how the event is viewed. A speaker can use imperfective morphology with a telic predicate ('She was building the house when it collapsed'), coercing the predicate out of its default telic reading. Conflating the two produces systematic errors in cross-linguistic analysis.

Question 4

The same verb can appear in different Aktionsart classes depending on the full predicate context — for example, 'push a cart' (activity) versus 'push a cart to the door' (accomplishment).

• T. True
• F. False

Answer: True

This is crucial: Aktionsart is a property of the full predicate, not just the bare verb. Adding a goal phrase ('to the door'), a quantized object ('a house' vs. 'houses'), or a result state converts an atelic predicate into a telic one. This compositionality of aspect — called 'aspectual coercion' or 'telicity shift' — shows that Aktionsart is not a fixed lexical property of verb roots but emerges from the entire VP. The diagnostics must be applied to full predicate phrases, not bare verbs.

Question 5

Why is the telicity distinction — whether a predicate has a natural endpoint — important for predicting how a verb will interact with grammar?

Model answer: Telicity determines how a predicate interacts with time adverbials, tense-aspect morphology, and entailment patterns in principled ways. A telic predicate in the simple past entails that the endpoint was reached ('She built the house' implies completion). An atelic predicate in the simple past does not entail any completion ('She ran' makes no claim about reaching a goal). This contrast drives the 'in an hour' vs. 'for an hour' distribution, the progressive entailment test (accomplishments under progressive entail partial completion of the endpoint; achievements do not), and cross-linguistic variation in how perfectivity is encoded. Telicity is not just a classification label — it is an explanatory variable for a wide range of grammatical phenomena.

The practical payoff of the Aktionsart framework is precisely its predictive power. Once you know a predicate's temporal class, you can predict a cluster of grammatical behaviors, not just classify it into a box. This is why Vendler's analysis was theoretically important: it connected what seemed like unrelated grammatical facts (progressive oddness with states, 'in'/'for' distribution, perfect entailments) to a single underlying parameter — the internal event structure of the predicate.
