Some authors call this type of grammar a right-regular grammar (or right-linear grammar) [1] and the type above a strictly right-regular grammar (or strictly right-linear grammar). [2] An extended left-regular grammar is one in which all rules obey one of A → w, where A is a non-terminal in N and w is in Σ * A → Bw, where A and B are in N ...

Example: Abdul is happy. Jeanne is a person. I am she. Subject + Verb (transitive) + Indirect Object + Direct Object Example: She made me a pie. This clause pattern is a derivative of S+V+O, transforming the object of a preposition into an indirect object of the verb, as the example sentence in transformational grammar is actually "She made a ...
Regular languages are commonly used to define search patterns and the lexical structure of programming languages. For example, the regular language = {| >} is generated by the Type-3 grammar = ({}, {,},,) with the productions being the following. S → aS S → a
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.
A formal language defined or generated by a particular grammar is the set of strings that can be produced by the grammar and that consist only of terminal symbols. Diagram 1 illustrates a string that can be produced with this grammar. Diagram 1. The string Б Б Б Б was formed by the grammar defined by the given production rules. This grammar ...
Now regular, formerly with Rückumlaut and metathesis of r and o: wreak – wreaked/wrought – wreaked/wrought: Weak: Usually regular; wrought (which is in fact from work) has come sometimes to be identified with this verb (perhaps by analogy with seek–sought). wring – wrang/wrung – wrung: Strong, class 3: write – wrote – written
