In linguistics, the topic (or theme) is the part of the proposition that is being talked about (predicated). Linguistics is the scientific study of Language, encompassing a number of sub-fields In traditional Grammar, a predicate is one of the two main parts of a sentence (the other being the subject, which the predicate modifies Once stated, the topic is therefore "old news", i. e. the things already mentioned and understood. For example, the topic is emphasized in italics in the following sentences:
The topic is also called theme, and the predicate that gives information on the topic is also called rheme.
A distinction must be made between the sentence-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.
Many languages, like English, resort to different means in order to signal a new topic, such as:
There are some other languages, like Japanese or Korean, that work directly on a topic-comment frame. is a language spoken by over 130 million people in Japan and in Japanese emigrant communities This article is mainly about the spoken Korean language See Hangul for details on the native Korean writing system A topic-prominent language is a language that organizes its Syntax so that sentences have a topic–comment (or theme–rheme structure in which the A new topic is always introduced in a specific way, like with a topic marker (Japanese uses a suffix, wa). A topic marker is a Grammatical particle found in the Japanese and Korean languages used to mark the topic of a sentence In Grammar, a suffix (also postfix, ending) is an Affix which is placed at the end of a word A topic marker is a Grammatical particle found in the Japanese and Korean languages used to mark the topic of a sentence The topic can be the subject or the object of a verb, but it can also be an indirect object or even an oblique complement of any kind. It is always dislocated to the front of the sentence.
Signaling the topic as such serves the pragmatic function of avoiding repetition. In many languages, old topics are replaced with a pronoun. In Linguistics and Grammar, a pronoun is a Pro-form that substitutes for a (including a noun phrase consisting of a single Noun) with or Pro-drop languages like Japanese tend simply to delete the old topic, which is then left implicit throughout the discourse until a new one appears. A pro-drop language (from "pronoun-dropping" is a Language in which certain classes of Pronouns may be omitted when they are in some sense pragmatically
