Mini Lesson
Most academic English vocabulary is built from Greek and Latin roots, so many English words have a cognate in Spanish, French, or Italian. A root carries the core meaning, while prefixes shift it and suffixes change its grammatical role. When you analyze a long word into its parts, you can often decode its meaning even if you have never seen the word before.
Greek roots — building blocks of science and ideas
- graph (write / draw) — autograph, polygraph, seismograph, choreography
- phon (sound) — phonics, polyphonic, cacophony, megaphone
- bio (life) — biology, biome, antibiotic, symbiosis
- geo (earth) — geology, geothermal, geopolitics
- tele (far) — telephone, telescope, telegraph
Latin roots — building blocks of action and law
- port (carry) — transport, deport, portable, rapport
- dict (say / tell) — predict, contradict, verdict, dictate
- rupt (break) — interrupt, erupt, disrupt, bankrupt
- aud (hear) — audience, auditorium, audible, audition
- scrib / script (write) — describe, transcript, manuscript, prescription
- vid / vis / spect (see / look) — video, visible, evidence, spectator, inspect
- mit / miss (send) — transmit, dismiss, omit, admission
Take the word spectator and break it into its parts.
What does spectator literally mean?
Now try the same method on misanthrope: mis (hate) + anthrop (human) = "one who hates humans."
Words to know
root
The base part of a word that carries its core meaning.
e.g. The Latin root "port" means carry, as in transport and portable.
prefix
A word part attached to the beginning of a root that modifies its meaning.
e.g. The prefix "trans-" means across, as in transport.
suffix
A word part attached to the end of a root that often signals its part of speech.
e.g. The suffix "-able" turns a verb into an adjective: portable.
morpheme
The smallest unit of language that carries meaning.
e.g. "Un-", "happy", and "-ness" are three morphemes in unhappiness.
cognate
A word that shares a root or origin with a word in another language.
e.g. "Familia" in Spanish is a cognate of "family" in English.
academic vocabulary
Words used frequently in textbooks and formal writing.
e.g. "Hypothesis" and "analyze" are academic vocabulary.
When you meet a long word, peel it like an onion: take off the prefix, take off the suffix, and look at the root in the middle. The root almost always carries the central clue.
Guided Practice
Read the story. As you read, notice how Sofia analyzes each word into prefix + root + suffix. How does this method help you understand new vocabulary?

Exercises
Tap a tile, then tap a slot. Build each academic word from its morpheme parts.
Build the word that means "light writing" — a picture taken with a camera.
Tile bank
Build the word for a device that carries sound from far away — built from "far" + "sound".
Tile bank
Build the word for "the study of life" — used as the name of a science subject.
Tile bank
Build the word for a book of "word sayings" — used to look up meanings.
Tile bank
Build the word that means "writing about the Earth" — used for the study of maps and continents.
Tile bank
Build the word for a "carry-able" object — small enough to take anywhere.
Tile bank
Use the root meaning given to complete each word.
Pick the best answer.
1. In the word "biography," which two roots combine, and what does the word literally mean?
2. Which word does NOT contain the root "spect" meaning "look"?
3. A "polygraph" is a device that detects lies by recording physical signals. Using the roots, what does the word literally mean?
4. The roots "vid" and "vis" both mean "see." Which sentence uses a "vid/vis" word correctly?
5. You meet the new word "audiologist." Using roots, what is the BEST inference?
6. Which set of words ALL share the same root meaning?
7. Why is knowing roots especially useful in Grade 5 reading?
8. The word "transmission" combines which parts?
