The Word-Root Shortcut
A student is working through an analogy section and encounters the pair: fractious : agreeable. She does not know the word fractious. She notices the second word, agreeable, means pleasant or easy to get along with. She also knows the root fract- appears in fracture and fraction. She guesses that fractious means something like 'broken apart' and therefore the relationship is one of opposition. She marks the answer as an antonym pair. Later she sees the pair fractious : quarrelsome and is unsure whether her original reasoning holds.
1. Evaluate the student's reasoning from root to meaning to relationship. Where is it sound and where is it risky?

Her root clue is sound: fract- relates to breaking. Her inference is plausible but not certain - a word built on 'break' could mean broken, divisive, or irritable. She correctly identifies that agreeable is positive, so an opposition is a reasonable hypothesis. The risk is treating a root guess as proof. Roots suggest meaning; they do not guarantee it. She should test the guess against the second pair rather than commit.
2. For *fractious : quarrelsome*, what should she conclude about her earlier antonym reasoning?
Read the worked answer
Quarrelsome means inclined to argue - negative and divisive, which fits 'breaking apart' socially. So fractious is closer to quarrelsome than to agreeable. Her earlier pairing was wrong about the relationship, even though the root guess was roughly right. The lesson: a root can point toward a meaning family, but the relationship type must be verified against a second pair. She should revise: fractious : agreeable is an antonym pair, but fractious : quarrelsome is a synonym pair. Both can be true because the words differ.
