How would you diagram a noun of diect address?

To diagram a noun of direct address, start by placing the sentence's main subject and verb in the usual subject-verb format. The noun of direct address should be set off by a comma and positioned either before or after the subject. For example, in the sentence "Lisa, can you help me?" the Word "Lisa" would be placed above the baseline and connected to the subject. This visual separation emphasizes that it is not part of the main sentence structure but is addressing someone directly.
