Step 1: Understanding the Concept:
This problem requires identifying an antonym, which means selecting the word that holds the exact opposite meaning of the provided word. Analyzing Latin roots can help us quickly determine the core action of the word.
Step 2: Detailed Explanation:
Let's analyze the structural origin of the word impede:
- It comes from the Latin word "impedire", which translates to "to shackle or entangle the feet" (im- meaning "in" + pes/pedis meaning "foot").
- In modern English, to impede means to delay, slow down, block, or obstruct the progress or movement of something or someone.
Since the word means to create obstacles or make a task more difficult, its true antonym must mean to help, support, or make a task easier:
- "Assist" (Option C) means to give help, support, or aid to a person or process, allowing things to move along smoothly. This is the exact opposite of blocking progress.
- "Obstruct" (Option A), "Delay" (Option B), and "Prevent" (Option D) are all direct synonyms that match the meaning of creating barriers.
Step 3: Final Answer:
The word opposite in meaning to impede is Assist.
