+# Spell Checker Using Tkinter
+
+## Overview
+
+This project is a simple **Spell Checker** built using **Tkinter**, a GUI library in Python. The spell checker compares user-inputted words with a list of pre-defined words stored in a file named `words.txt`. If a word entered by the user doesn't match any word in the list, it is flagged as a misspelled word.
+
+## Features
+
+- **Graphical User Interface (GUI):** Built using Tkinter, the interface allows users to input text and check for spelling mistakes.
+- **Text Comparison:** Words inputted by the user are compared against a predefined list of 300 words stored in `words.txt`.
+- **Misspelled Word Highlighting:** If the user inputs a misspelled word, the program informs the user that the word is not found in the word list.
+
+## How It Works
+
+1. **`words.txt` File:** 
+    - A text file (`words.txt`) contains a list of 300 common English words. This file serves as the dictionary that the program uses to verify the spelling of words.
+
+    Example of a few words from `words.txt`:
+    ```
+    apple
+    banana
+    computer
+    python
+    technology
+    ...
+    ```
+    The complete file includes a wide range of words covering categories such as animals, objects, professions, and more.
+
+2. **Tkinter GUI:**
+    - A GUI is designed with `Tkinter`, allowing the user to input a sentence. The program then checks each word against the list in `words.txt`.
+    - The result will display whether each word is correct or if it is misspelled.
+
+3. **Spell Checker Logic:**
+    - The program reads the `words.txt` file and stores the words in a list.
+    - The input provided by the user is split into individual words.
+    - Each word is compared with the list of words from `words.txt`. If the word is not found, the program flags it as a misspelled word.
+
+
+## How to Run the Project
+
+1. Clone the repository or download the project files.
+2. Make sure the `words.txt` file is in the same directory as the Python script.
+3. Run the `spell_checker.py` script using Python:
+    ```
+    python spell_checker.py
+    ```
+4. Enter a sentence or a group of words in the input field of the GUI and click "Check Spelling."
+5. The program will highlight any misspelled words.
+
+## Requirements
+
+- Python 3.x
+- Tkinter library (included with Python)
+
+## Future Enhancements
+
+- **Dynamic Word Suggestions:** Add functionality to suggest correct words for misspelled words.
+- **Custom Dictionary:** Allow users to add words to their custom dictionary.
+- **Advanced Spell Check:** Include handling of punctuation and more advanced grammar rules.
