Code to parse wikipedia's list of spelling correction into a format that @TheTypoMaster's code can understand. The headers / footers must be removed manually.

spelling-list-parser.cs

using System;
using System.IO;

public class Program
{
	public static void Main()
	{
		StreamReader source = new StreamReader("wikipedia-spelling-corrections.txt");
		StreamWriter dest = new StreamWriter("wikipedia-spelling-corrections-new.txt");
		while(!source.EndOfStream)
		{
			string nextLine = source.ReadLine();
			string[] parts = nextLine.Split('	');
			if (parts.Length != 2)
			{
				Console.WriteLine("Length was {0}, not 2.", parts.Length);
				return;
			}

			dest.WriteLine("{0} - {1}", parts[1], parts[0]);
		}

		source.Close();
		dest.Close();
		
		Console.WriteLine("Done.");
	}
