How is a synonym different from a related word?

Synonyms share meaning; related words just share a topic. Chilly is a synonym of cold, but snow is only a neighbor. The swap test exposes the difference: "a snow morning" doesn't say what "a chilly morning" says.

What makes a good synonym question hard?

Tempting foils. Our items pair the right answer with words that are related, opposite, or simply familiar, so students must check meaning instead of picking the word they've seen most. That checking habit is the real outcome.

How to teach this

Push one notch of richness at a time: happy to cheerful before happy to elated. When a foil is related but not synonymous (cold for winter), ask "same meaning, or just same topic?" That distinction is where 3rd grade synonym work actually lives.

Watch for: Synonyms mean almost the same, not exactly the same. Big and gigantic are both large, but gigantic is bigger. A word about the same topic isn't a synonym: orange isn't a synonym for pumpkin just because pumpkins are orange.
