It includes the F.F.1 list with 1,500 high-frequency words, completed by a later F.F.2 list with 1,700 mid-frequency words, and the most used syntax rules. [12] It is claimed that 70 grammatical words constitute 50% of the communicatives sentence, [13] [14] while 3,680 words make about 95~98% of coverage. [15] A list of 3,000 frequent words is ...
A defining vocabulary is a list of words used by lexicographers to write dictionary definitions. The underlying principle goes back to Samuel Johnson's notion that words should be defined using 'terms less abstruse than that which is to be explained', [1] and a defining vocabulary provides the lexicographer with a restricted list of high-frequency words which can be used for producing simple ...
Linguistics is the scientific study of language. [1] [2] [3] The areas of linguistic analysis are syntax (rules governing the structure of sentences), semantics (meaning), morphology (structure of words), phonetics (speech sounds and equivalent gestures in sign languages), phonology (the abstract sound system of a particular language, and analogous systems of sign languages), and pragmatics ...
These include Basic English (850 words), Special English (1,500 words), General Service List (2,000 words), and Academic Word List. Some learner's dictionaries have developed defining vocabularies which contain only most common and basic words. As a result, word definitions in such dictionaries can be understood even by learners with a limited ...

Context-free grammars arise in linguistics where they are used to describe the structure of sentences and words in a natural language, and they were invented by the linguist Noam Chomsky for this purpose. By contrast, in computer science, as the use of recursively-defined concepts increased, they were used more and more.
It is sometimes referred to as "isolated word recognition" because it involves a reader's ability to recognize words individually from a list without needing similar words for contextual help. [1] LINCS continues to say that "rapid and effortless word recognition is the main component of fluent reading" and explains that these skills can be ...
An extensional definition gives meaning to a term by specifying its extension, that is, every object that falls under the definition of the term in question.. For example, an extensional definition of the term "nation of the world" might be given by listing all of the nations of the world, or by giving some other means of recognizing the members of the corresponding class.
