It is known as cohesion to the action and effect of adhering things together, whether material or immaterial, such as ideas. The word cohesion is of Latin origin “cohaesum”.
In the area of grammar, textual cohesion, also known as lexical cohesion, is the union between words, paragraphs, and sentences, through the use of connectors, pronouns, synonyms, antonyms, hyperonimia, hyponymy in order to avoid constant use of words but maintaining a coherent idea for the reader.
For example: Carlota prefers to eat an ice cream. She likes chocolate flavored, and that one is buttered.
Cohesion synonyms are union, bond, connection, attraction, affinity, etc.
In sociology, social cohesion refers to the union that exists between the members of a group that share ideas, and have a sense of belonging, which allows to carry out a common project or purpose.
Social cohesion can occur in a work group, students. As well as, in a city, town, or country in which civil servants who occupy public office with society work for the common good of all, avoiding inequalities and discrimination between individuals.
Finally, the term under study was coined by the sociologist Emilio Durkheim.
Cohesion in physics
In physics, molecular cohesion is the molecular attraction between the molecules of the same body. In this sense, it can be said that cohesion is the property that keeps the solid body preserved in its shape, and strong to resist the pressures or applications of external forces.
For example, in ice, cohesion is caused by a decrease in the temperature that hardens and coalesces the water molecules, making them solid.
Cohesion and coherence
Consistency, as such, is the union that must exist between the ideas of a text, presenting unity and global meaning in it. For this, the correct use of the resources presented by cohesion is necessary, which are essential to form the relationships between the elements of a text.
Some of the cohesion resources are repetition, in the case of emphasizing an idea, replacing words with synonyms or antonyms, the use of pronouns, conjugations, grammatical links, etc.
