The idea of nexus It is used in the field of grammar to refer to the element that relates words, phrases and sentences thanks to its syntactic function. Depending on its characteristics, it is possible to differentiate between disjunctive ties , adversarial links , conditional links , consecutive links , explanatory links , subordinate ties and temporary links , among others.

On this occasion we will focus on the copulative links , also known as copulative conjunctions . These links allow join homogeneous components in the same sentence .
The copulative links serve to create a list of terms . Its inclusion allows the addition of elements that acquire a joint meaning.
For example: “Esteban and Bruno confirmed their attendance at the party”. As noted, the copulative nexus "and" serves to mention that two people ("Stephen" and "Bruno") confirmed that they will attend a certain event.
In order not to produce a cacophony, the copulative nexus "and" becomes "and" if the second term begins with the letter I (or with a H followed by I ): "Sociologists and historians met to discuss the new habits brought about by technological changes", “Mother and daughter decided to take a trip together”, “Pablo and Ismael went to the theater”.
It is important to mention that the addition propitiated by a copulative nexus can be negative . In the sentence “My nephew does not work or study”, the copulative nexus "neither" It links two actions that an individual does not perform: work and study. The meaning of the expression is equivalent to “My nephew does not work and does not study” (here the copulative link that is used is "and").
