Before 1066, English was a Germanic language. The words that survived from that older English are still the ones you reach for first: house, drink, eat, fight, begin, understand. Short. Physical. Blunt. They're the words children learn, the words you think in, the words that carry weight without effort.
German Roots is a 1,000-word vocabulary course built on this Anglo-Saxon foundation. An English course, taught through the building blocks the language inherited from its oldest ancestors.
The pack covers the prefixes, suffixes, and root words that form the backbone of everyday English:
Prefixes like fore-, over-, un-, mis-, out-
Suffixes like -ness, -dom, -ful, -ish, -hood, -ly
Root words that recur across hundreds of compounds and derivations
Once you see the pattern, you stop memorizing words one at a time. You start recognizing families. Forethought, foresight, foreword, forecast — one prefix, one logic, four words you no longer need to look up.
For native English speakers, German Roots is a course in the etymology of your own language. Most of the words you use every day come from this layer, but you've never been shown the seams. This pack makes the structure visible.
For ESL learners from northern Europe — Dutch, German, Scandinavian, Frisian — German Roots is a bridge. You already know half these roots from your own language. You just haven't been shown the crossing. This pack makes the connection explicit and turns shared ancestry into an unfair advantage.
1,000 words across 5 tiers of ~200 words
48 thematic clusters of about 20 words each
Every card includes a definition, an example sentence, and notes on usage
Master 80% of a cluster to unlock the boss fight
Defeat the boss to graduate the cluster permanently
Spaced repetition on Fibonacci intervals — the better you know a word, the longer before you see it again
Reading level sits around B2 / sixth-to-eighth grade. Accessible from the start, with no prerequisite packs.
German Roots is the first of three etymological vocabulary packs for English:
German Roots — the Anglo-Saxon layer.
Norman Roots — the French layer that arrived in 1066. Government, law, cuisine, social register.
Latin Roots — the scholarly layer. Scientific, medical, and academic vocabulary built from Latin prefixes and stems.
Each pack stands alone. Together they cover the three vocabularies that English is built from.
1,000 English words organized by Germanic root
5 tiers, 48 thematic clusters, 48 boss fights
Spaced repetition tuned for long-term retention
