Here's why:
* Tone refers to the author's attitude towards their subject matter. It's conveyed through their word choice, sentence structure, and overall style.
* Tone can be formal, informal, humorous, serious, sarcastic, passionate, objective, etc.
For example:
* Formal tone: "The issue of climate change is a critical one that demands immediate action."
* Informal tone: "Seriously, we gotta do something about this climate stuff, it's getting crazy!"
* Humorous tone: "I'm pretty sure my car's air conditioning is fueled by fossil fuels, because it's hotter inside than outside."
* Serious tone: "The consequences of inaction on climate change are dire, and we must act now to protect our planet."
Understanding the tone helps readers grasp the writer's perspective and interpret their message effectively.
