Word type: Dorsal is primarily used as an adjective.
Meaning: Dorsal refers to the back or upper surface of an animal, plant, or organ. In a broader sense, it can also mean situated on or toward the back or posterior part of an organism.
Word history: The term dorsal comes from the Latin word dorsalis, which means of or pertaining to the back.
It entered the English language in the late 16th century and has since been widely used in biology and anatomy.
Synonyms: Some synonyms for dorsal include posterior, back, and spinal. However, it’s important to note that these words are not always interchangeable and may have specific uses in different contexts.

Examples use in sentences: Let’s look at how dorsal can be used in various contexts. The dorsal fin of a dolphin helps it maintain stability while swimming.
