Usage Note: Together with is often used following the subject of a sentence or clause to introduce an addition. The addition, however, does not alter the number of the verb, which is governed by the subject: The king (singular), together with two aides, is expected soon. The same is true of along with, besides, and in addition to. See Usage Notes at besides, like2.
