Capitalization

Q. Does CMOS allow random capitalization in poems?

A. We would, provided the randomness worked on some level. If a publisher has accepted the poem, then it probably does. A copyeditor might query any choice that doesn’t seem to be intentionally random—on the off chance that it might be a mistake—but otherwise, it’s usually up to The PoET.

[This answer relies on the 17th edition of CMOS (2017) unless otherwise noted.]
