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

How to Use

Pandas:

df = pd.read_csv("/content/llm_english_100MB.csv")
df.head()

Hugging Face Datasets:

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.
