Atreemology teaches you the roots English words grow from: plant one, watch it branch into a dozen words you'll actually remember, and build a personal forest as you go.
Works in any browser. No sign-up, no ads, no credit card.
No flashcard decks to grind through. Just a root, a tree, and a habit that adds up.
Every lesson starts with one word root: a small, real piece of English with a clear meaning, like "spec" (to look) or "bene" (good).
Learn the words that share that root (spectator, inspect, benefit, benevolent) and watch your root grow into a full tree, branch by branch.
Finished trees join your forest: a visual record of every root you've mastered, not just a number going up.
Words come back for review right before you'd naturally forget them, using spaced repetition under the hood.
Every root is hand-verified, not auto-generated, so the words it grows are ones you can trust.
Grows into predict, dictate, and verdict.
Grows into spectator, inspect, and perspective.
Grows into benefit, benevolent, and benediction.
Grows into telephone, television, and telegraph.
"Benediction" comes from both bene (good) and dict (to speak), so it renders as a real branch connecting those two trees in your forest, right on screen. It's proof the roots actually connect, not just a trivia note in a sidebar.

Progress you can actually look at: every finished tree stays in your forest for good.
Words come back for review right before you'd forget them, so you never have to think about scheduling it.
