# LLM-English-100MB — Compact & Dense English Teaching Corpus

A 100MB, extremely clean CSV designed to teach an LLM English from scratch via instruction-tuning. No noise, no HTML, no duplicates — just pure grammar, vocabulary, and syntax transformations.

Generated with a single paste-and-run Python script in Google Colab.

### Why this teaches English

Instead of raw text, the dataset is **instruction -> input -> output** pairs that force the model to learn rules:

- **Grammar Mechanics:** tense conversion, negation, question formation, active/passive, subject-verb agreement, article & preposition usage, contraction
- **Vocabulary:** pluralization, synonyms, antonyms, definitions, comparatives
- **Error Correction:** common ESL mistakes with corrected form + rule

Each row includes an explicit `rule` column so the model learns the *pattern*, not just memorizes.

### Dataset Schema

Extremely clean: UTF-8, LF (`\n`), `QUOTE_MINIMAL`, no empty fields, no newlines inside fields.

| Column | Type | Description |
| :--- | :--- | :--- |
| `id` | int | Unique row ID |
| `level` | string | CEFR level: A1, A2, B1, B2 |
| `category` | string | `grammar`, `vocabulary`, `syntax` |
| `task_type` | string | e.g. `tense_past`, `pluralization`, `negation`, `question_formation`, `comparative`, `active_passive`, `article_usage`, `synonym`, `antonym` |
| `instruction` | string | What the model must do |
| `input_text` | string | Input sentence / prompt |
| `output_text` | string | Correct target |
| `rule` | string | Short linguistic rule |

Example:
```
instruction: Convert to simple past tense.
input_text: We build the house.
output_text: We built the house.
rule: build -> built
```

### Stats

- **Size:** 100 MB (configurable)
- **Rows:** ~650k - 750k (avg ~150 bytes/row)
- **Format:** CSV
- **Encoding:** UTF-8
- **Generation Time:** ~90-120 seconds on Colab

### How to Use

**Pandas:**
```python
import pandas as pd
df = pd.read_csv("/content/llm_english_100MB.csv")
df.head()
```

**Hugging Face Datasets:**
```python
from datasets import load_dataset
ds = load_dataset("csv", data_files="/content/llm_english_100MB.csv")["train"]
# Format for instruction tuning: instruction + input -> output
def format_prompt(ex):
    return {"text": f"### Instruction: {ex['instruction']}\n### Input: {ex['input_text']}\n### Output: {ex['output_text']}"}
ds = ds.map(format_prompt)
```

**Training Prompt Template:**
```
Below is an instruction that teaches English.

### Instruction:
Convert to simple past tense.

### Input:
She eats the apple.

### Output:
She ate the apple.
```

### Quality Guarantees — EXTREMELY CLEAN

- No HTML, no URLs, no emojis
- No nulls / NaNs
- Stripped whitespace, no `\r`, no `\n` inside fields
- Deterministic seed (42) for reproducibility
- Validated with `csv.DictReader`
- All rows are synthetic and license-free

### Customize

Edit vocab lists at top of script:
```python
NOUNS = [...]
VERBS = [...]
```

Add new generators to `GENERATORS` list to add new task types.
