Synonym text list of common English words

get the data from http://dictionary-thesaurus.com/wordlists.html (for example)  copy to some txt files and import into your DB

if you need "merriam-webster" like database, there are probably for $ software that includes some db

Not sure if you're serious in regard to the thesaurus.com link. I really cannot make any sense of what you wrote.

Are you actually suggesting to ask for each word, then copy that one word at a time, then insert another, over a thousand times?

You must mean something else, and if so, please explain in some detail what you mean.

In the meantime, the question is still wide open for suggestions. But obviously, I need a fully loaded and completed text file with the words and synonyms already populated.

As far as I know, no such text file exists.  However there ARE freeware thesaurus programs and files availabe.

Your other option is to search in a thesaurus. Thesaurus.com (link below) not only gives you the main word and it's synonyms and antonyms,  it also gives you related words and their synonyms. This will make it faster for you to build lists of adjectives and their synonyms you want.

Copy and paste the results you want to keep into a text file.  For an excellent freeware notepad replacement and text editor with MANY features, I highly recommend TED Notepad.

My question stated that I had already looked at  WordNet. I wrote, "Note that I've already looked at wordnet.princeton.edu but there is no such list ".

 I wanted a text list of common words with a synonym for each; one word, one synonym, or in database format I can easily extract into such a list.

I already know how to use a thesaurus  so most of these links and ideas are not at all helpful. They are incredibly basic and rudimentary, and don’t come even close to giving me a list. Yes, one can create their own but that’s why I came here, so I would find one already created. I don’t have time for the days it would take to manually search for words and their synonym counterpart and to make my own list. Such a list could have many thousands of adjectives and even verbs with synonyms for each. I’m surprised that in the entire world of the web, there is no such list. Otherwise someone surely would have found.

So, I don’t see any suggestions that come close to any answer I can use, so no points.  If there really is no such list, perhaps if I did make such a list, I could sell it.

For those interested, here's a link to a small list, but one that shows what I want. There are two columns but I have my choice of which to use, and all I have to do is cut and paste, plus a couple minutes of text editing:

http://www.synonyms-antonyms.com/english-synonyms.html

No additional synonym lists from anyone so time to close.
