دریا is the Persian word for "sea" or "ocean." It refers to large bodies of saltwater that cover significant portions of the Earth's surface. Seas are vital for marine life, climate regulation, and human activities such as fishing and transportation. In Persian culture, دریا holds symbolic meanings, often representing vastness, depth, and mystery. It is frequently featured in literature and poetry, reflecting the beauty and power of nature. The Persian Gulf and the Caspian Sea are notable examples of دریا in the region, each with unique ecological and cultural significance.
