Conclusion indicators are words or phrases that signal a conclusion in a Formal Logic I argument. They point you to the statement the premises are meant to support.
Conclusion indicators are words or phrases in Formal Logic I that tell you, "this is the conclusion." They help you spot the claim an argument is trying to prove, instead of mixing it up with the reasons given for it.
Common conclusion indicators include words like therefore, thus, hence, so, and as a result. If you see a sentence with one of these markers, there is a good chance the statement right after it is the conclusion, though the exact structure still matters. For example, in "The library is closed, therefore we should study elsewhere," the second part is the conclusion.
This works because formal logic is less about the topic being discussed and more about the structure of support. The premises are the reasons, and the conclusion is the claim being supported. Conclusion indicators make that support easier to map out when you are reading ordinary language arguments that are not already written in symbols.
Not every conclusion is tagged with a neat signal. Some arguments leave the conclusion unstated, and some use the same words in non-logical ways, like "so" in everyday conversation. That is why you still have to read for the overall direction of the argument, not just hunt for one keyword.
You may also run into complex arguments with more than one conclusion. In those cases, conclusion indicators can help you see which claims are intermediate steps and which one is the main point. That matters when you are trying to diagram an argument or separate a chain of reasoning into smaller parts.
A good habit in Formal Logic I is to treat conclusion indicators as clues, not proof. They usually point you to the conclusion, but the sentence still has to fit the role of a claim being supported by the premises.
Conclusion indicators matter because argument analysis starts with finding the conclusion. If you misidentify the main claim, the rest of your work goes off track, whether you are diagramming the argument, deciding whether the support is strong, or translating the statement into symbols.
In Formal Logic I, a lot of classwork asks you to separate premises from conclusions before you can judge validity or soundness. Conclusion indicators give you a fast entry point into that process. They do not replace careful reading, but they make it easier to trace the structure of everyday arguments that are written in normal English instead of symbolic notation.
They also matter when an argument is longer than one sentence. Some passages contain sub-conclusions, where one claim is established first and then used as a premise for the final conclusion. Spotting indicator words can show you the order of the reasoning, which is especially useful in complex argument and serial argument work.
If you are analyzing a class discussion, editorial, or short passage, conclusion indicators help you explain why a statement counts as the main claim. That is a useful skill in logic because the subject is really about how support is arranged, not just whether a statement sounds persuasive.

Premises are the reasons an argument gives, while conclusion indicators point to the claim those reasons are trying to support. When you read an argument, the indicator word often helps you separate the supporting statements from the statement being supported. That distinction is the first step in almost every structure question in Formal Logic I.
Argument
An argument is a set of statements where some are offered as support for another. Conclusion indicators help you identify the end point of that support. Once you know which statement is the conclusion, you can start asking whether the argument is valid, whether the premises actually fit, and whether any hidden assumptions are doing work.
Complex Argument
Complex arguments often contain more than one conclusion, especially when one claim is used to reach another claim later on. Conclusion indicators help you spot those layers. In a long passage, a statement with therefore or thus might be an intermediate conclusion, not the final point of the whole argument.
Premise Indicators
Premise indicators work in the opposite direction from conclusion indicators. Words like because, since, and for often introduce reasons rather than the main claim. Comparing the two types of indicator words makes it easier to diagram arguments quickly and avoid swapping the support with the claim.
A quiz or problem-set question may give you a short passage and ask you to identify the conclusion first. You use conclusion indicators as a clue, then check whether the sentence after the indicator is really the main claim or just a smaller step in the reasoning. On longer argument-analysis prompts, you may need to label premises, conclusion, and any intermediate conclusions.
If a passage has no obvious indicator words, you still have to infer the conclusion from the overall structure. That usually means asking, "What is the author trying to get me to accept?" If your instructor gives a diagramming exercise, this term helps you decide where the argument ends before you draw the support lines.
Conclusion indicators are words or phrases that usually signal the main claim in an argument.
They do not prove that a sentence is the conclusion, but they are a strong clue when you are analyzing ordinary-language arguments.
Formal Logic I uses conclusion indicators to separate the claim being supported from the premises that give support.
Longer arguments can contain more than one conclusion, so you may have to identify both intermediate and final claims.
Good argument analysis uses indicator words plus the overall logic of the passage, not indicator words alone.
Conclusion indicators are words or phrases that point to the statement an argument is trying to prove. In Formal Logic I, they help you identify the conclusion so you can separate it from the premises. Common examples include therefore, thus, hence, and as a result.
Common examples are therefore, thus, hence, so, and as a result. In a sentence like "The roads are icy, therefore we should drive slowly," the indicator word therefore signals that the second part is the conclusion. The exact wording can vary, so you still need to check the argument’s structure.
Conclusion indicators point to the claim being supported, while premise indicators point to the reasons supporting it. Words like because, since, and for often introduce premises, not conclusions. If you mix them up, you can diagram the argument backwards.
Then you have to find the conclusion by reading for the statement that the rest of the passage is trying to support. Formal Logic I often uses unstated or implied conclusions, so the absence of a signal word does not mean there is no conclusion. It just means you need to rely more on the argument’s structure.
