An antecedent is a text fragment, sentence or word that is referred to by another phrase or word. It can be a person or an event that happened in the past, and that can help explain the present. Another name for this term is a referent.
The most common type of this device is a noun related to a pronoun that is mentioned afterward. From a grammar aspect, it's crucial for the pronouns and their antecedents to agree both in number and in gender to avoid any possible confusion. This is especially important in sentences or phrases that contain more than one pronoun.
The term "antecedent" is of Latin origin and can be loosely translated as "the one that comes before." This term is actively used in multiple fields including philosophy, grammar studies, and literary sciences.
It's important to see the difference between the antecedent and the consequent. While the former describes something that happened prior to the situation in question, the latter is the outcome of the mentioned event. For example, in a conditional sentence of the "If A happens, then B will occur" type, "A" is the antecedent, while "B" is the consequent. "A" is the word or phrase that is tied to the word "if" and the consequent is the part of the sentence that continues after the word "then."
Additionally, it's crucial to note that it's not enough to establish a grammar link between a clause and a consequent to create an antecedent, as they should be logically connected. A sentence like "If Marry adopts a child, it will rain in Paris for a year" doesn't make any logical sense, as the antecedent doesn't have any relation to the supposed consequent.
In most cases, pronouns are related to nouns that are situated before them in a sentence. However, even though usually the literal translation of this term accurately describes the use of this tool, sometimes an antecedent can be located after the word or phrase that refers to it. For example: "For all his good intentions, Gatsby had no idea that his decision will have such a tragic outcome."
There are also situations where multiple antecedents exist in a single sentence. Such an occurrence makes it harder for the reader to follow the author's chain of thought and understand which pronoun relates to which noun. The works of the literary realism movement are exceptionally rich with such examples, due to the attention to detail that the authors of that time are known for.
For instance, in Charles Dickens' "Great Expectations" we can find such a sentence: "When I had gone into Herbert's room, and had shut off any other communication between it and the staircase than through the room in which our conversation had been held, I asked him if he would go to bed?" As evident from this example, the reader has to follow both the referents of the pronoun "it" and the adjective "Herbert's" to understand the second part of the sentence.
The primary purpose behind the use of an antecedent is to explain the reader the meaning of a pronoun and to whom or what it refers to. If a pronoun or phrase is left unrelated to a subject, it may create confusion, as the reader won't know which character is doing what.
In literary sciences, an antecedent isn't limited to a single phrase or sentence but can be used to describe an entire situation that represents the reason for an event or a problem. For example, a dramatic scene may be a result of the previous actions taken by a character that led to the unfolding of the situation in a question. In this case, the actions that may have occurred several chapters before the conflict escalation are the antecedent of the current event.
In an even broader sense, an antecedent is also an event that is described in the first chapters of a literary work but has occurred prior to the beginning of the book. Authors add such passages to help the reader understand the initial disposition of certain characters or forces in a story or to add more context to the setting.
The use of such a device is especially prevalent in high fantasy novels that offer the reader a lot of exposition due to their unfamiliarity with the world in front of them. J.R.R. Tolkien has dedicated numerous pages to describing antecedent events that happened before the start of the main storyline of "The Lord of The Rings." Before the actual plot begins, the reader learns the history of the hobbit race. And as the story progresses, he is continuously fed additional information about what happened prior to the events of the first book.
