Application Strategy for Etymological Word Decoding
When encountering an unfamiliar word in an NTS stem or option:
- Isolate the Root: Look for familiar letter combinations inside the word (e.g., IM-PLAC-ABLE $\rightarrow$ PLAC = please/soothe).
- Determine Prefix Influence: IM- = NOT. Therefore, IM-PLAC-ABLE = NOT able to be pleased/soothed (unyielding).
- Match Tone and Context: Check if the sentence requires a negative adjective describing a person's unyielding nature. Select the choice that aligns with this etymological breakdown.
