How to create a wordlist recogniser

Hi,



I am an assistant professor and I am working on a new method of learning English or any other languages.

I have a word list of 1000 words. like this:

a (an)

able

about

account

acid

across

act

across

act

addition

…

I want to choose or create some texts including only the words of my word list. So I need a program to help me to recognize any other words out of the list, like the Microsoft Word that underlines any misspelled words.

I have seen the help of the Microsoft Word that suggest creating a custom dictionary, but

1. I do not have a custom dictionary; I only have a word list.

2. More important is this problem that the Microsoft Word does not remove its main dictionary; therefore I could not recognize the words out of my list.

3. If I choose German, for example, as the main language of the computer and add the words of my list to it, what about the common words between German and English?

I want you to help me in this problem. I want you to give me a step by step solution, and if possible, examine the solution yourself to be sure it is successful.



Thanks a lot

Ali
