đại dương

Friendly

The Vietnamese word "đại dương" translates to "ocean" in English. It refers to the large bodies of saltwater that cover most of the Earth's surface. In total, there are five main oceans on our planet: the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern Ocean, and Arctic Ocean.

Usage Instructions:

• "Đại dương" is a noun and can be used in both everyday conversation and more formal writing.
• You can use it to talk about marine life, geography, and environmental topics.

Example:

• "Đại dương có nhiều loài cá và sinh vật biển." (The ocean has many species of fish and marine creatures.)

Advanced Usage:

• In literature or poetry, "đại dương" can symbolize vastness, depth, or the unknown. For example:
  • "Tâm hồn của tôi như đại dương, sâu thẳm và bí ẩn." (My soul is like the ocean, deep and mysterious.)

Word Variants:

• "Biển" is another Vietnamese word that means "sea," which is smaller than an ocean. While "đại dương" refers to large expanses of saltwater, "biển" can refer to both seas and oceans in a more general sense.

Different Meanings:

• "Đại dương" specifically means "ocean" and does not have multiple meanings. However, it can be used metaphorically to describe something vast or limitless.

Synonyms:

• "Biển" (sea) - while it generally means a smaller body of saltwater, it can sometimes be used interchangeably in casual contexts.
• "Sóng" (waves) - while not a synonym for "đại dương," it is often used in discussions about oceans since waves are a characteristic feature of them.
