Usage

Since plus as a preposition has long had the meanings “more by the addition of ” and “with the addition of,” it was but a short step to a newer use, mainly in informal writing and speech, as a conjunction meaning “also, and, furthermore.” Although this use is increasing, many object to it, and it is rare in more formal writing. And plus is likewise objected to, especially for being redundant: The paper was delivered two hours late, and plus it was soaking wet.

Plus, together with, and along with do not create compound subjects in the way that and does: the number of the verb depends on that of the subject to which plus, together with, or along with is added: this task, plus all the others, was (not were ) undertaken by the government; the doctor, together with the nurses, was (not were ) waiting for the patient
