"The study by Dr. Aris et al. revolutionized the field."
Illustration
e.g.
exempli gratia
Literal: "For the sake of example"

Definition
i.e.
id est
Literal: "That is"
Think "in essence." Used to clarify or specify exactly what you mean.
"The flight is at noon, i.e., 12:00 PM."
The Style Manual
Punctuation
Always follow e.g. and i.e. with a comma. Ensure every period is included correctly.
Redundancy
Never write "and etc." because "et" already means "and." It would be like saying "and and the rest."
Ending Lists
If you use "e.g." at the start of a list, don't use "etc." at the end. One implies examples; the other implies a total set.
💡 i.e. = In Essence / e.g. = Example Given
👥 et al. = "And all" (the people)

Email Disaster Diagnostics
1. Error: "i.e., social media, email marketing..."
Correction: Use e.g.,
Reason: "i.e." (id est) means "that is" and is for definitions. The author is listing examples, which requires "e.g." (exempli gratia).
2. Error: "e.g., the whole department."
Correction: Use i.e.,
Reason: The author isn't giving an example; they are clarifying/defining exactly who the "stakeholders" are. "i.e." is used for specifying the exact set.
3. Error: "etc. Sarah and Jackson."
Correction: Use et al.
Reason: "etc." is for objects. "et al." (et alii) is specifically for people.
4. Error: "et al. vegan and gluten-free options."
Correction: Use e.g., or etc.
Reason: "et al." is for people. These are food items/objects. "e.g." would introduce them as examples, or "etc." could end a list of foods.

Decoding the Latin of Logic and Argumentation
The "Attack" Argument
ad hominem
"Why should we listen to your plan for the environment? You can't even keep your own front yard tidy!"
— A Common Attack
Literal Meaning
"To the man."
The Concept
Attacking a person's character instead of their argument.
The "Wait, What?"
non sequitur
Literal Meaning
"It does not follow."
The Concept
A conclusion that has nothing to do with the premise or previous statement.
"It's raining outside; therefore, we should definitely buy more library books today."
— A Logical Leap
The "False Cause"
post hoc ergo
"The rooster crowed, and then the sun rose. Therefore, the rooster's crow caused the sunrise!"
— Correlation vs. Causation
Literal Meaning
"After this, therefore because of this."
The Concept
The fallacy of assuming that because Event B happened after Event A, Event A must have caused Event B.
The Power of "Therefore"
ergo

— René Descartes
"I think, therefore I am."
Use ergo when you want to signal a final, undeniable logical conclusion in your writing.
Your Case Study
"Senator Miller supports the tax cut. But Senator Miller once failed a math test in high school. Miller's math is bad; ergo, the tax cut will destroy the economy. The last time Miller proposed a bill, it rained for a week straight! Don't let Miller ruin our weather again."

Identify the Latin rhetorical term that best describes the logical error or structural signal being used.

Exhibit B
"Ever since the city installed those new LED streetlights last month, my cat has been acting very strange and won't eat her dinner. Those lights are clearly emitting some kind of frequency that is upsetting her appetite."

The Mission
As a lead editorialist, your voice has the power to shift public opinion. However, persuasion requires more than just passion; it requires intellectual authority and logical precision . Your final task is to write a 300-400 word editorial that takes a clear stance on a contemporary issue while integrating the Latin phrases we have studied throughout this unit.
Core Objectives
Take a definitive stance on a debatable topic.
Use evidence and logical reasoning to support your claim.
Seamlessly integrate mandatory Latin terminology.
Ensure correct punctuation and professional tone.

The Writing Process
1
Identify the Gap
Choose a topic where the de jure (rules) and the de facto (reality) don't match up. This creates a strong argument.
2
Build the Logic
Construct a series of points that lead to an ergo moment. Avoid logical fallacies like non sequiturs.
3
Cite Authority
Quote a source verbatim to ground your argument in evidence, not just opinion per se.
