Alternatives doesn't indicate terms that should not be used

The 'Alternative' category in the .R files does not delineate between terms that should and should not be used. Alternatives, perhaps this should be renamed and/or a new category should be added such as synonyms. I am just trying to work out how users will know which term they should use if an alternative also has a definition and the words are essentially synonyms. Or, would the previous NEVER happen because synonyms would only be listed in the alternative category and not have their own .R file. This is coming up for me because of forecast vs. projection. They are not really alternatives of each other but I would like some way to link them so users know they should look at both definitions before deciding which term applies to their situation.

Review the Alternative category in the .R files, starting with the forecast and projection terms described in the issue. Decide how the dictionary should distinguish preferred terms from synonyms or other related alternatives, and consider whether the category name or an additional category needs to change; the work is done when users can tell which terms to use and which definitions to compare.
