Why do so many school words come from Greek and Latin?

English borrowed its scholarly vocabulary from Latin and Greek for centuries, so science, math, and history terms still carry those parts. That's actually good news: a student who knows forty common roots holds a key to thousands of academic words.

How do roots help on reading tests?

Unfamiliar-word questions usually hide a familiar root. A student who spots cred in credible or chron in chronological can reason out the answer without ever having studied the word itself. That's the skill these items rehearse, one sentence at a time.

How to teach this

Ask for the evidence: when a student picks hydrant, have them name the root and its meaning aloud. Word detective habits form here. Wall charts of root families grow nicely all year, and inventing silly new words from real roots (a chronoscope? a biograph?) proves they own the system.

Watch for: A root isn't a prefix; it's the core of the word. Prefixes and suffixes attach to it (in-spect-ion). Knowing one root unlocks a family of words, not just one: port gives transport, export, import, and portable.
