argument

The word "argument" has a surprisingly broad range of meanings. At its core, an argument is a reasoned case for or against a particular proposition, action, or belief. This could be a formal debate, like those held in courtrooms or political arenas, where participants present evidence and logic to persuade others. For example: "The lawyer presented a strong legal argument to the jury."

However, "argument" also commonly refers to a disagreement or quarrel—often involving raised voices and conflicting opinions. This is the meaning most people associate with the word. Think of siblings arguing over a toy, or friends disagreeing about which movie to watch. "They had an argument about politics and haven't spoken since."

Interestingly, in academic writing or literature, an "argument" refers to the main point or thesis. It is the central idea or claim that a writer is trying to prove to the reader. A historian might write a book where their central argument is that economic factors caused a specific war.

In math and computing, an "argument" can also mean an input to a function, method, or command. For example: "This function takes two arguments," or "Run the program with the --verbose argument."

The key to understanding which meaning is intended lies in the context. Is someone building a case with evidence? Are they disagreeing heatedly? Or are you identifying the main claim of an essay? Whether it's a logical presentation, a fiery debate, or the backbone of a written work, an argument always involves presenting ideas and attempting to persuade others—even if you're trying to persuade yourself.
