Latin and Greek Roots

A root word is the basis of a word and it typically does not stand alone. More than half of the words in the English language have Latin or Greek roots – this is especially true in content areas such as science and technology. Starting in Grade 5, students encounter about 10,000 new words in their reading. Teaching Greek and Latin root words helps students to more quickly decipher the meaning of unfamiliar words and is an effective strategy for word comprehension and vocabulary building.
