Why are there so many dictionaries on the market ? Rated 3 out of 5 stars

Because not all definitions are alike, and that choosing one dictionary rather than another is like choosing one Bible edition rather than another.
Therefore, what dictionary does this add-on refer to ? This is the first question I had in mind when discovering this add-on. I am surprised the information is not provided.
3 stars, neutral
