1) it's all about the dictionnary
let's admit that we have two textbox
<one> you write the english word I am
<two> you write the french word Je suis
Create a button that do:
On clicked do: dictionnary -> add key -> key name = texboxone.text and value = textboxtwo.text
With this you get
I am = Je suis
I need = J'ai besoin
Or whatever you want.
2) It's where is became easely it's a simple matcher
If every list.selectedText = good value in dictionnary so "WIN"
Because of the language barrier if you dont understand what i say or you thinks i dont understand what you say, you can retry to ask in another way.
