First, let me correct your question please. When you are asking about meaning, use this format: "What does "[word/phrase]" mean?". So in this case, the correct question would be "What does "as well as" mean?" The answer is that "as well as" has two meanings: 1. "As well as" is a phrase used to compare how skillfully two people do the same thing. Example 1: Jason plays violin as well as Martha (meaning they are equally skilled) Example 2: Brandon doesn't play the violin as well as Jason (meaning that Jason is better at violin playing than Brandon) 2. "As well as" can also mean "in addition to". Example: Brandon, as well as Martha, are going to the movies tonight. Note: This sounds sort of formal, I don't think you'll hear it very often.
