In linguistics Linguistics is the scientific study of natural language. Linguistics encompasses a number of sub-fields. An important topical division is between the study of language structure and the study of meaning (semantics and pragmatics). Grammar encompasses morphology (the formation and composition of words), syntax (the rules that determine how words, the topic (or theme) is informally what is being talked about, and the comment (rheme or focus) is what is being said about the topic. Although this general nature of topic-comment dichotomy is generally accepted, anything beyond that is a matter of great controversy.

The distinction was probably first suggested by Henri Weil Henri Weil was a German-born French Jewish philologist in 1844. Georg von der Gabelentz distinguished psychological subject (roughly topic) and psychological object (roughly focus). In the Prague school The Prague Linguistic Circle or "Prague school" was an influential group of literary critics and linguists in Prague. Its proponents developed methods of structuralist literary analysis during the years 1928–1939. It has had significant continuing influence on linguistics and semiotics. After World War II, the circle was disbanded but, the dichotomy, termed topic-focus articulation, has been studied mainly by Vilém Mathesius, Jan Firbas, František Daneš, Petr Sgall and Eva Hajičová Eva Hajičová is a Czech linguist, specializing in topic-focus articulation and corpus linguistics. In 2006, she was awarded the ACL Lifetime Achievement Award. They have been concerned mainly by its relation to intonation and word-order. The work of Michael Halliday in the 1960s is probably responsible for bringing the ideas to Functional Grammar Functional Grammar and Functional Discourse Grammar (FDG) are grammar models and theories motivated by functional theories of grammar. These theories explain how linguistic utterances are shaped, based on the goals and knowledge of natural language users. In doing so, it contrasts with Chomskyan transformational grammar. Functional Discourse.

Note that in some categorizations, topic refers only to the contrastive theme and comment to the noncontrastive theme + rheme.

Definitions

The term "topic" can be defined in a number of different ways. Among the most common are

In an ordinary English sentence, the subject is normally the same as the topic. For example, the topic is emphasized in italics in the following sentences:

Although these sentences mean the same thing, they have different topics. The first sentence is about the dog, while the second is about the little girl.

In English it is also possible to use other sentence structures to show the topic of the sentence, as in the following:

A distinction must be made between the clause-level topic and the discourse-level topic. Suppose we are talking about Mike's house:

In the example, the discourse-level topic is established in the first sentence: it is Mike's house. In the following sentence, a new "local" topic is established on the sentence level: he (Mike). But the discourse-level topic is still Mike's house, which is why the last comment does not seem out of place.

Realization of topic/comment

Different languages Language is a term most commonly used to refer to so-called "natural languages" — the spoken forms of communication ubiquitous among humankind. By extension the term also refers to the type of thought process which creates and uses language. Essential to both meanings is the systematic creation, maintenance and use of systems of mark topics in different ways. Distinct intonation and word-order are the most common means. The tendency to place topicalized constituents sentence-initially (topic fronting) is widespread. Again, linguists disagree on many details.

Languages often show different kinds of grammar for sentences that introduce new topics and those that continue discussing previously established topics. When a sentence introduces a new topic for discussion, it is most likely to use one of the strategies mentioned in (b), or (c) above.

When a sentence continues discussing a previously established topic, it is likely to use pronouns to refer to the topic. Topics of this sort show a tendency to be subjects, as mentioned in (a) above. In many languages, pronouns referring to previously established topics will show pro-drop.
