Word Radicals: Latin & Greek

Every English word has a story. Word Radicals lets you read it.

Type an English word and instantly see the Greek and Latin roots it's built from, with each root's meaning and the ancient word it traces back to. Or go the other way: look up a Greek or Latin word and see exactly what it means and which English words descend from it. It's a dictionary that works in both directions.

WHAT YOU CAN DO

• Break down English words: "photography" comes from photo- (light) + -graphy (writing), from Greek phos and grapho.
• Look up 44,000+ real Latin and Ancient Greek words, with definitions and principal parts.
• Explore whole word families: one root like graph- opens onto dozens of related English words.
• See real inflection paradigms, printed with proper macrons and accents.
• Search naturally: type Greek in the Latin alphabet ("logos" finds the Greek), accents are optional, and even inflected forms resolve to their dictionary word.

LEARN IT, DON'T JUST LOOK IT UP

• Study the most productive Greek and Latin roots with built-in flashcards.
• Spaced repetition schedules each card for the moment you're about to forget it.
• A Word of the Day widget puts a new root on your home screen every morning.

BUILT RIGHT

• Completely offline. No account, no sign-in, no ads, no tracking.
• Fast, native, and designed for reading, in light and dark mode.

Whether you're studying for the SAT or GRE, learning Latin or Greek, decoding medical and scientific vocabulary, or simply curious why English words mean what they mean, Word Radicals turns everyday words into a window on two ancient languages.
