How the sentences are built
Each sentence is assembled from word banks — people and animals, things, adjectives, verbs with all their forms, places, time phrases, adverbs and conjunctions — following English sentence patterns: subject + verb + object, optionally with an adverb, a place and a time. Verbs are conjugated to match the subject and tense (the baker bakes, the bakers bake, the baker baked, the baker is baking), and articles switch between a and an automatically. The results are grammatical but often delightfully odd — which makes them good prompts.
Sentence types
| Type | Pattern | Example |
|---|---|---|
| Simple | One independent clause | The tiny artists shared a shiny painting under the bridge. |
| Compound | Two independent clauses joined by and, but or so | The explorer nervously washed a little sandwich on the train, so the noisy dragon hid a colourful umbrella in the kitchen. |
| Complex | An independent clause and a dependent clause (because, while, although, when, after) | After the quiet teachers wrote a broken umbrella by the river, the neighbour eagerly lost a wooden lantern at the market. |
These examples were generated by the same word banks and rules the tool uses.
Ways to use random sentences
| Use | How |
|---|---|
| Story starters | Generate one sentence and write what happens next |
| ESL grammar | Change the tense, make it negative, or turn it into a question |
| Parts of speech | Turn on highlighting and identify each word type |
| Sentence expansion | Add who, where, when and why to a level 1 sentence |
| Handwriting | Print a worksheet and copy sentences neatly |
| Typing practice | Copy fresh sentences so you can’t rely on memory |
| Drawing games | Illustrate the sentence — the stranger, the better |
Worked example
A teacher sets level 2, past tense and complex sentences for a grammar lesson. One sentence reads: “After the quiet teachers wrote a broken umbrella by the river, the neighbour eagerly lost a wooden lantern at the market.” Students identify the subordinating conjunction, rewrite the sentence in the present progressive, and then flip the clauses around (or back), noticing that a comma is needed when the dependent clause comes first. The teacher prints the set of five as a worksheet for homework.
Turning a sentence into a lesson
- Identify: find the subject, verb and object.
- Transform: change the tense — past, present, progressive.
- Negate: add “did not”, “does not” or “is not”.
- Question: turn it into a yes/no question and a wh- question.
- Expand: add an adjective, an adverb, a place and a time.
- Combine: join two sentences with and, but, so or because.
- Illustrate: draw it, then label the parts of speech.
Each step takes only a minute or two, and together they make a complete short grammar lesson from a single generated sentence.

Level guide
| Level | What’s included | Good for |
|---|---|---|
| 1 | Subject, verb, object | Early readers, beginner ESL, handwriting |
| 2 | Adds place phrases and some adverbs | Grammar practice, typing warm-ups |
| 3 | Adds time phrases; longer sentences | Writing prompts, advanced ESL, dictation |
Combine the level with the sentence type: level 1 simple sentences suit young learners, while level 3 complex sentences stretch confident writers.
Punctuation rules the sentences follow
- A compound sentence uses a comma before and, but or so when joining two full clauses.
- A complex sentence that starts with the dependent clause (Because…, While…) needs a comma after it.
- When the dependent clause comes second, no comma is usually needed.
- Every sentence starts with a capital letter and ends with a full stop.
