Conjunction, from the Latin coniunctĭo, is a joint or union. Specifically, this Latin word is made up of three clearly delimited parts: the prefix “with”, which is synonymous with “completely”; the word “iugum”, which is equivalent to “yoke”, and finally the suffix “-ción”, which can be translated as “action and effect”.
According to DigoPaul, the term is used in astronomy and linguistics, among other areas. For example: “The astronomers reported that the conjunction between Mercury and Venus will occur tomorrow”, “I have to explain what a coordinating conjunction is”, “The teacher said that next semester we will study the conjunctions”.
An astronomical conjunction is the relative situation of two or more stars when, from an observation point, they are aligned. The concept is also used to name the aspect of two stars that occupy the same celestial house.
It is possible to speak of inferior conjunction or superior conjunction. The lower conjunction occurs when the planets inside Earth’s orbit pass between the Earth and the Sun, causing these planets to be close to the Earth and display their unlit side.
The higher conjunction, on the other hand, occurs when the Sun is between the inner planets and the Earth. In this case, the planets reach their maximum distance from Earth.
A grammatical conjunction, on the other hand, is an invariable word that heads a subordinate sentence or that joins syntactically equivalent sequences or words. A conjunction links words, phrases, or propositions.
Specifically, we would have to determine that there are two large groups of conjunctions. On the one hand, there are the coordinators and on the other, the subordinates.
Among the most important types of conjunctions within the grammatical scope are the following:
• Adversative, which is one that comes to reveal a confrontation or difference between the two sentences. Examples are “however”, “but”, “however”, “except”…
• Comparison. It is the one that, as its name suggests, is used to compare both phrases. In your case, we would have to underline “how”.
• Conditional, which is the conjunction that makes clear a condition that must be met for a consequence to take place. An example of this type is “yes”.
• Copulative, which we can say comes to “add” the two sentences. In this case, the types of conjunctions are four: “and”, “e”, “ni” and “that”.
• Disjunctive, which is the one that comes to express the opposition of two sentences or the alternation or exclusion of one of them. There are two: “o” and “u”.
“Al”, “por”, “para”, “so”, “although” and “but” are examples of conjunctions: “At sunset, vampires come out of their caves”, “You are not going to train with us for being late ”, “ We are here to help ”, “ The decision has been made so don’t insist ”, “ Even though you made a mistake, you are going to have another chance ”, “ It was not Ricardo who hit Juan, but Pedro ”.
To all this we would have to add that the term at hand is also used in mathematics. In his case, there is what is known as a “logical conjunction”, which makes it clear that an operator is true if both operators are also true.
