also
In addition; used to add another thing or idea.
Also means in addition to something else, or too. When you say “I like pizza, and I also like tacos,” you're adding tacos to your list of favorite foods. When your friend says “I'm going to the library” and you respond “I'm going also,” you mean you're going there too.
The word helps you add information without starting a whole new sentence. Instead of saying “I finished my homework. I cleaned my room,” you can say “I finished my homework and also cleaned my room.” It makes your speech and writing flow more smoothly.
You'll often see also at the beginning of sentences when someone wants to add another point: “The museum has dinosaur fossils. Also, they just opened a new space exhibit.” Here it works like saying “additionally” or “and another thing.”
Writers try not to overuse also so their sentences don't sound repetitive. They might mix it up with words like “too,” “as well,” “in addition,” or sometimes just “and.” All of these help connect ideas clearly.
