I am seeking help for a program I am trying to make. First Off, my goal is to make a converter that will convert words you type in to another word... As in
If I typed In "and" and wished to convert it to "plus" or "also".... How would I go about doing this. My second question is.. If the first part was completed.. how would I make the converter use 2 to 3 options of a word to convert to....... example... If I had a paragraph with about 12 "then" words in it.. I would possibly want to use a variety of words like that.. so I would enter the paragraph into the converter and it would convert all of the "then" words to a conversion of random words Like "after" or "later"

Another example:
Before: Then he went to the park. Then he drove his car. Then he went home.

After. Then he went to the park. After he drove his car. Later he went home.

Is there any way of doing this?? The first question being answered is fine.. the second is just something that could be added. Thanks
