Traditional grammar (also known as classical grammar) is a framework for the description of the structure of a language or group of languages. [1] The roots of traditional grammar are in the work of classical Greek and Latin philologists. [2] The formal study of grammar based on these models became popular during the Renaissance. [3]
In computer science, a Van Wijngaarden grammar (also vW-grammar or W-grammar [1]) is a formalism for defining formal languages. The name derives from the formalism invented by Adriaan van Wijngaarden [2] for the purpose of defining the ALGOL 68 programming language. The resulting specification [3] remains its most notable application.
Grammar rules may concern the use of clauses, phrases, and words. The term may also refer to the study of such rules, a subject that includes phonology, morphology, and syntax, together with phonetics, semantics, and pragmatics. There are, broadly speaking, two different ways to study grammar: traditional grammar and theoretical grammar.
A weighted context-free grammar (WCFG) is a more general category of context-free grammar, where each production has a numeric weight associated with it. The weight of a specific parse tree in a WCFG is the product [ 7 ] (or sum [ 8 ] ) of all rule weights in the tree.
It is decidable whether a given grammar is a regular grammar, [f] as well as whether it is an LL grammar for a given k≥0. [26]: 233 If k is not given, the latter problem is undecidable. [26]: 252 Given a context-free grammar, it is not decidable whether its language is regular, [27] nor whether it is an LL(k) language for a given k.
In linguistics and grammar, a sentence is a linguistic expression, such as the English example "The quick brown fox jumps over the lazy dog." In traditional grammar , it is typically defined as a string of words that expresses a complete thought, or as a unit consisting of a subject and predicate .
A sentence diagram is a pictorial representation of the grammatical structure of a sentence. The term "sentence diagram" is used more when teaching written language, where sentences are diagrammed. The model shows the relations between words and the nature of sentence structure and can be used as a tool to help recognize which potential ...
