Root Words is a free daily etymology game that teaches you the building blocks of the English language. Each day you are given a Latin or Greek root along with its meaning, and your goal is to find as many English words as possible that contain that root. It is a fun, timed challenge that naturally expands your vocabulary and deepens your understanding of where words come from.

A new root is available every day on Gamesite. Play in your browser on any device — no account or download needed. Whether you are a student, a language enthusiast, or just curious about words, Root Words makes learning etymology genuinely enjoyable.

How to Play

A root and its meaning are displayed — for example, "CHRON" meaning "time."
You have 90 seconds to find as many English words as possible containing that root.
Type a word and press Enter. Valid words must be at least 4 letters and exist in the dictionary.
Points are awarded by word length: 1 point for 4-5 letters, 2 for 6-7, 3 for 8 or more.
When the timer runs out, see your final score and all the words you found.

Tips & Strategy

Start with the most obvious words first — if the root is "BIO," "biology" and "biography" should come immediately.
Think about common prefixes and suffixes. Adding "un-," "re-," "-tion," "-ology," or "-ical" to a root often yields valid words.
Do not forget less common but valid words. Scientific and medical terms frequently use Latin and Greek roots.
Longer words score more, but do not waste time on one long word when three short ones earn more total.
Play daily to build your root vocabulary. Over time, you will start recognizing roots in unfamiliar words — a genuine superpower for reading comprehension.
