This interaction of additional semantic features with argument structure requires a device that can relate two non-sister nodes in a sentence to an earlier step in the derivation of a phrasal structure. Withal, referring to the history of the derivation of a phrase structure cannot be conveyed using a context-free phrase structure grammar.
For example, changing a complex sentence into two simpler sentences while maintaining the overall meaning falls into this category. Discourse-based changes are alterations that affect the larger discourse or text structure, such as reordering points in a paragraph or changing the way arguments are presented without altering the factual content.
Phrase structure rules as they are commonly employed result in a view of sentence structure that is constituency-based. Thus, grammars that employ phrase structure rules are constituency grammars (= phrase structure grammars), as opposed to dependency grammars, [4] which view sentence structure as dependency-based. What this means is that for ...
One specific example is semantic change, which is a change in a single word's meaning. The boundary between word formation and semantic change can be difficult to define as a new use of an old word can be seen as a new word derived from an old one and identical to it in form.
The parse tree is the entire structure, starting from S and ending in each of the leaf nodes (John, hit, the, ball). The following abbreviations are used in the tree: S for sentence, the top-level structure in this example. NP for noun phrase. The first (leftmost) NP, a single noun John, serves as the subject of the sentence.
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 ...
Syntax refers to the linguistic structure above the word level (for example, how sentences are formed) – though without taking into account intonation, which is the domain of phonology. Morphology, by contrast, refers to the structure at and below the word level (for example, how compound words are formed), but above the level of individual ...
The garden-path sentence effect occurs when the sentence has a phrase or word with an ambiguous meaning that the reader interprets in a certain way and, when they read the whole sentence, there is a difference in what has been read and what was expected. The reader must then read and evaluate the sentence again to understand its meaning.
