A more thorough explanation:

Ergo is a Latin word that means "therefore" or "thus." It is often used to show a conclusion or result based on previous information.

For example, if someone says "I am allergic to peanuts, ergo I cannot eat peanut butter," they are using "ergo" to show that their allergy leads to the conclusion that they cannot eat peanut butter.

Another example is the Latin phrase "post hoc ergo propter hoc," which means "after this, therefore resulting from it." This phrase is used to describe a logical fallacy where someone assumes that one event caused another event simply because it happened after it. For instance, if someone says "I wore my lucky socks and then my team won, ergo my lucky socks caused the win," they are making a false assumption based on the order of events.

Overall, "ergo" is a useful word for showing logical connections between ideas, but it's important to use it correctly and avoid making false assumptions.
