The word "but" is a conjunction that helps connect two ideas, often showing contrast. For example, you might say, "I wanted to go for a walk, but it started to rain." Here, "but" highlights the unexpected change in plans due to the rain. It helps us understand that while one idea was positive, another situation changed everything. Using "but" can also help clarify our thoughts. For instance, you might say, "I like chocolate, but I prefer vanilla." In this case, "but" indicates a preference, showing that even though you enjoy one thing, there is something you like even more. This simple word helps us express complex feelings and choices.
