How to turn roots into hundreds of words
Next time you meet an unfamiliar word, don't reach for the dictionary right away. Break it into pieces first. Chronological? That's chron (time) + log (order) — something arranged in time. Hydrophobia? Hydro (water) + phobia (fear). Once the roots are yours, the words decode themselves.
