Lexical aspect

Lexical aspect is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lexical aspect rather than just read about it. In short: In linguistics, the lexical aspect, situation type or Aktionsart (German pronunciation: [ʔakˈtsi̯oːnsˌʔaːɐ̯t], plural Aktionsarten German pronunciation: [ʔakˈtsi̯oːnsˌʔaːɐ̯tn̩]) of an event is part of the way in which that event is structured in relation to time. For example, the English verbs arrive and run differ in their lexical aspect since the former describes an event which has a natural endpoint while the lat…

Key takeaways

Lexical aspect belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Lexical aspect to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Lexical aspect from memory before moving on to harder problems.

Reference excerpt

In linguistics, the lexical aspect, situation type or Aktionsart (German pronunciation: [ʔakˈtsi̯oːnsˌʔaːɐ̯t], plural Aktionsarten German pronunciation: [ʔakˈtsi̯oːnsˌʔaːɐ̯tn̩]) of an event is part of the way in which that event is structured in relation to time. For example, the English verbs arrive and run differ in their lexical aspect since the former describes an event which has a natural endpoint while the latter does not. Lexical aspect differs from grammatical aspect in that it is an inherent semantic property of a predicate, while grammatical aspect is a syntactic or morphological property. Although lexical aspect need not be marked morphologically, it has downstream grammatical effects, for instance that arrive can be modified by "in an hour" while believe cannot.

Theories of aspectual class Although all theories of lexical aspect recognize that verbs divide into different classes, the details of the classification differ. An early attempt by Vendler recognized four classes, which has been modified several times.

Vendler's classification Zeno Vendler classified verbs into four categories on whether they express "activity", "accomplishment", "achievement" or "state". Activities and accomplishments are distinguished from achievements and states in that the first two allow the use of continuous and progressive aspects. Activities and accomplishments are distinguished from each other by boundedness. Activities do not have a terminal point (a point before which the activity has taken place and after which it cannot continue: "John drew a circle"), but accomplishments have one. Of achievements and states, achievements are instantaneous, but states are durative. Achievements and accomplishments are distinguished from one another in that achievements take place immediately (such as in "recognise" or "find"), but accomplishments approach an endpoint incrementally (as in "paint a picture" or "build a house").

Comrie's classification In his discussion of lexical aspect, Bernard Comrie included the category semelfactive or punctual events such as "sneeze". His divisions of the categories were as follows: states, activities, and accomplishments are durative, but semelfactives and achievements are punctual. Of the durative verbs, states are unique as they involve no change, and activities are atelic (that is, have no "terminal point") whereas accomplishments are telic. Of the punctual verbs, semelfactives are atelic, and achievements are telic. The following table shows examples of lexical aspect in English that involve change (an example of a state is 'know').

Moens and Steedman's classification Another classification is proposed by Moens and Steedman, based on the idea of the event nucleus.

Worked examples

Example 1 — a first encounter with Lexical aspect

Start with the simplest possible case. Write down what Lexical aspect claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lexical aspect before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lexical aspect ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lexical aspect

In research: Lexical aspect appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Lexical aspect in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Lexical aspect is common in secondary-school and first-year university syllabi. It links to neighbouring topics Grammar, Syntax–semantics interface, Time in linguistics, so understanding it makes those chapters shorter.
In everyday life: Look for Lexical aspect outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
