Deconstructing "Marriage" (the poem's first disseminated signifier)
The poem's great aporia occurs because the speaker cannot name "Marriage." That unspeakable signifier disseminates the even more unspeakable signifier, "Wedding Night," and that signifier disseminates "Sexual Intercourse," the Elizabethans' "little Death," a source of "Pain" for virgin "Girls."
"Sexual Intercourse," of course, is the signifier which literally and figuratively disseminates "Girls" for "Men" to marry. The poem cannot name "Men," either, though they are necessary to make "Wife" in Dickinson's era, but "Men" do lurk in "Wife"'s cross-signifying claim to be "Czar."
