Fill in the blank with the correctly spelt word.
The astronomer studied the _______ movement of newly discovered celestial bodies.
Show answer & explanation
Correct answer: A
Explanation
Correct Answer: circumstellar
Explanation:
• The correctly spelt word is circumstellar, which means surrounding or orbiting a star (from Latin circum meaning 'around' and stellar relating to stars).
• Common errors occur in the suffix, often mistakenly written with -or, -er, or a single 'l' instead of the standard -ar ending (as in interstellar or stellar).
