When I look at the title i wonder why the poetest use an adjective like dead to refer to a word. She wants to give us some anticipations about the possible content of the poem.

Emily Dickinson focus the reader’s attention on the word.

With the title the reader makes conjectures about the possible contento f the poem and so he has a reason to read it.

 In this poem there are two verses each one has got three lines.

In the first two verses, there is a rhyming couplet (AA): dead - said.
