Greek and Latin Word Roots

Grade 4 · English · Study Guide

Discover how knowing Greek and Latin roots can help you figure out the meanings of unfamiliar words.

Many English words come from ancient Greek and Latin languages. When you know what a root word means, you can often figure out the meaning of an unfamiliar word without looking it up.

A root is the base part of a word that carries its core meaning. Prefixes are added to the beginning of a root, and suffixes are added to the end. Together, these parts build new words.

Some common Latin roots include: "port" (to carry), "rupt" (to break), "dict" (to say or tell), and "scrib/script" (to write). For example, "transport" means to carry across, and "interrupt" means to break into something.

Common Greek roots include: "bio" (life), "geo" (earth), "photo" (light), "graph" (to write), and "tele" (far away). "Biography" means writing about a life, and "telescope" means seeing things far away.

Learning roots is a powerful reading strategy. When you see a new word, look for parts you recognize. If you know "geo" means earth, you can guess that "geology" is the study of the earth. Building your root knowledge expands your vocabulary and helps you become a stronger reader and writer.
