For example, we say <span data-no-translation>in the river<\/span> for something inside the water, and <span data-no-translation>on the mountain<\/span> for something on its surface. Understanding the difference is important for clear communication in English. Think of <span data-no-translation>in<\/span> for being *inside* or *surrounded by* something, like <span data-no-translation>in the sky<\/span> o <span data-no-translation>in the forest<\/span>. Use <span data-no-translation>on<\/span> for being *on the surface* of something, like <span data-no-translation>on a tree<\/span> o <span data-no-translation>on the ground<\/span>. This lesson will help you use these prepositions correctly with common nature words at an A1 level, making your descriptions more precise and natural.<\/div>\n<h2>What Are Prepositions <span data-no-translation>in<\/span> y <span data-no-translation>on<\/span>?<\/h2>\n<p>Prepositions are small words that tell us about location, time, or direction. For example, they tell us <em>where<\/em> something is.<\/p>\n<p>Today, we focus on <span data-no-translation>in<\/span> y <span data-no-translation>on<\/span>.
