These two sentences have one difference: one has a comma. think about what each sentence means. 1. let's eat, grandma. 2. let's eat grandma. what does the first sentence mean? what does the second sentence mean?

Although both sentences include the exact same words, they have a different meaning due to the missing comma. In sentence 1, the speaker is inviting her grandmother to eat with him/her. On the other hand, in sentence 2, the speaker is telling someone to join him/her to eat a human being: her/his grandmother. Therefore, while in sentence 1 the word 'grandma' is in the vocative case, in sentence 2 the word 'grandma' in is the accusative case.  

In sentence 1, the speaker is inviting her grandmother to eat with him/her. On the other hand, in sentence 2, the speaker is telling someone to join him/her to eat a human being: her/his grandmother.
