Word Meaning Differences – How to Use Having, Holding, Giving, and Throwing Parties

Moreover and furthermore are essentially interchangeable synonyms. They're formal substitutes for additionally, also, as well, in addition to, likewise, and too. Those two words are common in academic prose, partially because writers don't combine sentences well or often enough, partly because they need to use them to keep their sentences short enough to read without causing reader fatigue, and partly because it's the easiest way of adding additional information. I try to eliminate as many instances of moreover and furthermore as possible, but it's sometimes impossible.

In addition, they emphasize the "too-ness" of what comes next: {Moreover/Furthermore}, Judge Jones owns stock in the defendant's company, so he should recuse himself from presiding over this case.

The one you use is pretty much a question of personal taste, but my rule of thumb is to put moreover first and furthermore second if the two appear in the same paragraph on in contiguous paragraphs. Others may have a different "rule", but I think it's strictly personal choice.

"To inaugurate" is fairly archaic in American English. We say people get inaugurated in political office, or to inaugurate a new policy. I couldn't tell you exactly what the difference is, but I can't remember the last time I heard someone use the word for anything but a new president.

To say something "launched" implies movement, and a certain element of risk. Its usage is metaphoric, as literally speaking only vessels launch. When you "launch" a new software, you are taking it from its safe harbor (the development team) and putting it out into the dangerous seas (the general public). It used to imply adventure and risk, but is now sufficiently commonplace that people don't normally think of it that way. "Released" is a more neutral word for the same thing.
