basically
In a simple way that gives only the main idea.
Basically means focusing on what's most important while leaving out extra details. When you say, “Basically, the book is about a girl who discovers she has magical powers,” you're giving the main idea without explaining every plot twist and character.
People use basically when they want to simplify something complicated. A science teacher might say, “Basically, photosynthesis is how plants turn sunlight into food,” skipping the complex chemistry to give students the essential concept first. When your friend asks what happened at lunch and you say, “Basically, everyone argued about which movie to watch,” you're summarizing the situation without repeating every single comment.
Sometimes people overuse basically as a filler word, saying it when they're not actually simplifying anything: “I basically went to the store.” In that sentence, basically adds nothing and weakens the statement. It works best when you're genuinely boiling something down to its essence: “Our basketball team basically won because we practiced our free throws every single day.” That use of basically points to the fundamental reason for success.
