The family tree has been rendered here as an Euler diagram without overlapping subareas. The wave model allows overlapping regions. In linguistics , the comparative method is a technique for studying the development of languages by performing a feature-by-feature comparison of two or more languages with common descent from a shared ancestor and ...
Family tree showing the relationship of each person to the orange person, including cousins and gene share. A family tree, also called a genealogy or a pedigree chart, is a chart representing family relationships in a conventional tree structure. More detailed family trees, used in medicine and social work, are known as genograms .
Grammar is the study of how meaningful elements called morphemes within a language can be combined into utterances. Morphemes can either be free or bound. If they are free to be moved around within an utterance, they are usually called words, and if they are bound to other words or morphemes, they are called affixes. The way in which meaningful ...
A sentence diagramis a pictorial representation of the grammaticalstructure of a sentence. The term "sentence diagram" is used more when teachingwritten 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 sentences ...
Language family. A language family is a group of languages related through descent from a common ancestor, called the proto-language of that family. The term family is a metaphor borrowed from biology, with the tree model used in historical linguistics analogous to a family tree, or to phylogenetic trees of taxa used in evolutionary taxonomy.
Syntax diagrams (or railroad diagrams) are a way to represent a context-free grammar. They represent a graphical alternative to Backus–Naur form, EBNF, Augmented Backus–Naur form, and other text-based grammars as metalanguages. Early books using syntax diagrams include the "Pascal User Manual" written by Niklaus Wirth [ 1] (diagrams start ...
Genogram. A genogram, also known as a family diagram, [ 1][ 2] is a pictorial display of a person's position in their family's hereditary and ongoing relationships. It goes beyond a traditional family tree by allowing the user to visualize social patterns and psychological factors that punctuate relationships, especially patterns that repeat ...
Comparative linguistics is a branch of historical linguistics that is concerned with comparing languages to establish their historical relatedness.. Genetic relatedness implies a common origin or proto-language and comparative linguistics aims to construct language families, to reconstruct proto-languages and specify the changes that have resulted in the documented languages.
