🔤 Word Detectives: Why We Say That!

What you’ll learn

1. Words Have Family TreesUnderstand that words have origins (etymology) and that many are built from smaller pieces or sounds.Words have histories, and the study of them is called etymology. Some words are compounds built from smaller words, like breakfast (break plus fast) and sunflower. Words can change meaning over time, like 'nice' once meaning silly. Some words, called onomatopoeia, were born by copying sounds, like buzz and splash.
2. Words From Faraway PlacesLearn that English borrows many words from other languages around the world.English borrowed thousands of words from other languages. 'Pajama' came from Persian, and 'ketchup' journeyed from an Asian fish sauce, changing along the way. Words like taco, pizza, and safari come from Spanish, Italian, and Swahili. English is like a mixing bowl full of words from all over the world.
3. Words From Names and PlacesDiscover that some words come from people's names (eponyms) and place names.Some words come from names. The sandwich is named after the Earl of Sandwich, and the teddy bear after President Theodore Roosevelt. Other words come from places: denim from the town of Nimes, hamburger from Hamburg, and jeans from Genoa. Names and places can turn into everyday words.
4. Be a Word DetectiveLearn how new words form (blends, invention) and how to use roots to decode word meanings.New words are born all the time, often as blends like brunch (breakfast plus lunch) or from new inventions like 'internet' and 'selfie.' Word roots help detectives decode meanings: 'tri' means three, 'aqua' means water, and 'phone' means sound. Spotting roots helps kids figure out big words on their own.
