"Content" is what is "contained" inside something. We usually use the plural "contents" when we talk about physical things, like the contents of a box or the contents of your refrigerator. "The contents of the box" means "everything inside the box." We can use the singular/non-count form ("content") for describing things that are not physical, like information in an essay, or images in a video. If a movie has "violent content," that means there are violent scenes in the movie. You are saying that the movie "contains" violence. "Context" is the information *around* something. The context is *outside* of the thing, not inside it. Context is outside information that helps us understand something. The meaning of a word (or an action) can change depending on the context it occurs in. For example, the word "we'd" can mean either "we had" or "we would" The word by itself does not tell us which meaning it has. But if you see a sentence like "We'd been to Spain twice," the context tells us that "we'd" must mean "we had," because "we would" does not make sense. The words "been to Spain twice" are the context. They are not part of the word "we'd," but they help us understand what "we'd" means. A context can also be a situation. For example, it might be okay to pat your friend on the shoulder, but inappropriate to pat your teacher on the shoulder. The action of patting someone's shoulder is the same in both situations, but the context is different. So if you ask, "Is it okay to touch someone's shoulder?", the answer is, "It depends on the context."

And also content :) when i see all these 3 words i just think one meaning is that is included in sth
