Pebb's English in Patterns and Examples

English pronunciation, grammar, and rhythm can seem random, but most of it actually follows patterns. Each circle collects one set of those patterns into its own short course, with interactive apps so you can practice what you learn right away, not just read about it.

Circles

Word Circle
12 spelling and pronunciation patterns - silent E, vowel teams, silent letters, and more. Includes 3 practice apps (an animated guide, an ear-training drill, and a word-unlocking puzzle game) plus a written reference guide.
Open
Stress Circle
Which syllable gets the beat, and why - word-class patterns, suffix rules, and prefixes and compounds, each with a tap-through animated guide.
Open
Melting Circle
How English's small words - he's, gonna, wouldn't've - actually sound in connected speech, one mumble at a time.
Open
Gravity Circle
Every tense, every auxiliary, every pronoun, in mumble - statement, negative, and question, for the whole verb system.
Open
Chanky Circle
How speakers cut sentences into chunks: one spotlight word, gray words that shrink, and where the boundaries are allowed to go.
Open
Tonal Circle
The melody of speech - how pitch rises and falls on a chunk's spotlight word, and what each direction signals.
Open
Full Circle
One idea, poured into every mold - statement, negative, question, command - and the toolkit for saying it politely.
