Latin Lives On

Derivatives, mottoes, and roots.

What you'll learn

  • Spot English words from Latin roots
  • Translate common Latin phrases
  • Use roots to decode new words
The dead language in your mouth

You use Latin daily without knowing — 'etc.', 'vice versa', 'video' (I see). Latin lives on inside English and the sciences; spotting its roots unlocks the meaning of thousands of words at once.

You already speak some Latin

Latin never fully died — it lives inside English. Huge swaths of our vocabulary, especially in science, law, and academia, come from Latin roots. Knowing a root unlocks whole families of words: from aqua (water) come aquarium, aquatic, and aqueduct.

  • video, I see → video, evident, vision
  • porto, I carry → portable, import, transport
  • scribo, I write → scribe, describe, manuscript
Latin in plain sight

Mottoes and abbreviations surround us: e.g. (exempli gratia, 'for example'), etc. (et cetera, 'and the rest'), and e pluribus unum ('out of many, one') on coins.

Lab · Root detective
  1. Take the root aud- (from audire, to hear).
  2. List three English words that contain it (for example: audio, audience, audible).
  3. Guess the meaning of an unfamiliar word, 'inaudible,' using the root plus the prefix in- (not).
  4. Do the same with the root spect- (to look): find two words and decode 'spectator.'

What you should see: You used Latin roots to build word families and to decode unfamiliar English words — the practical payoff of studying Latin.
