Learn Arabic: Astronomy Words

This lesson introduces the essential Arabic vocabulary needed to navigate the cosmos, from the familiar celestial bodies of our solar system to the distant reaches of the universe (al-kawn). For centuries, Arabic-speaking scholars led the world in astronomical discovery, making these terms culturally significant as well as scientifically practical. You will learn to identify the planets, such as Mars (al-mirrīkh) and Jupiter (al-mushtarī), as well as complex phenomena like a black hole (thuqb aswad) or a nebula (sadīm).

One fascinating linguistic pattern to notice is the relationship between the words for planet (kawkab) and asteroid (kuwaykib). The latter is a diminutive form, a common feature in Arabic where the internal vowel structure of a noun is modified to denote a smaller version of the original object. Additionally, this list highlights the distinction between solar and lunar letters in the definite article. In the word for Sun, ash-shams, the sound of the letter L in the prefix "al-" is assimilated into the following letter, while in al-qamar (the moon), the L remains clearly pronounced. You will also encounter logical compound descriptions, such as the term for a satellite (qamar ṣināʿī), which literally translates to an "artificial moon," and the evocative name for the Milky Way, darb at-tabbānah. Mastering these words provides a foundation for discussing science, nature, and the wonders of space (faḍāʾ).
