“And” is the conjunction we use to add information. However, sometimes we use other phrases, such as “along with,” “in addition to,” “as well as,” “with,” “including” and “together with.” These seem to add information but, in fact, don’t.
Why do you care? Whether you use “and” or one of the other phrases determines whether the sentence is singular or plural. Look at the following two sentences:
1. Clark Kent, Jimmy Olsen and Lois Lane work at the Daily Planet.
2. Clark Kent, together with Jimmy Olsen and Lois Lane, works at the Daily Planet.
That “and’ in the first sentence makes the subject plural; it includes all three people Therefore, the verb also has to be plural. In the second sentence, “together with” does not make Jimmy and Lois part of the subject. Only Clark is the subject; therefore, you need the singular verb works.
