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.
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.
A semantic treebank is a collection of natural language sentences annotated with a meaning representation. These resources use a formal representation of each sentence's semantic structure. Semantic treebanks vary in the depth of their semantic representation.
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 ...
Derivation can be contrasted with other types of word formation such as compounding. Derivational affixes are bound morphemes – they are meaningful units, but can only normally occur when attached to another word. In that respect, derivation differs from compounding by which free morphemes are combined (lawsuit, Latin professor).
These pairs of sentences have the same information structure, expressing the same communicative intention of the speaker, because the part immediately preceding the verb is left unchanged. The emphasis can be on the action (verb) itself, as seen in sentences 1, 6 and 7, or it can be on parts other than the action (verb), as seen in sentences 2 ...

Rather, the object is held figuratively, and then another verb is acted on the object. [citation needed] SOV structure is widely used in railway contact in order to clarify the objective of the order. [12]
