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. An effective strategy for word comprehension and vocabulary building is to become familiar with frequently-used roots. This helps students to more quickly decipher the meaning of unfamiliar words.

Many ELL students' first language is based in Latin, so teaching roots helps them connect new English vocabulary to words in their native language. Research also indicates that struggling readers benefit from a focus on learning Greek and Latin roots.
