In poetry what is the "part of speech" for the following passages?“Love like a burning city in the breast.” --Edna St. Vincent Millay “I’m...

I will help as I can; here are definitions of literary
devices that should identify all of the quotes. With those I'm not sure about, I've
entered possibilities. Even when doing research, not all websites
agree...

SIMILE: Those quotes
that use "like" to compare two dissimilar things are similes. (I think there are three
of these...but not Lewis.)

METAPHOR:
Comparisons that are made without using "like" or "as" are metaphors.
Example: "You are the sunshine of my
life."

APOSTROPHE: Not to be
confused with the punctuation mark, apostrophe is the act of addressing some abstraction
or personification [person] that is not physically
present

PERSONIFICATION: A
href="http://web.cn.edu/kwheeler/tropes.html">trope
in which abstractions, animals, ideas, and inanimate objects are given human character,
traits, abilities, or reactions. Personification is particularly common in poetry, but
it appears in nearly all types of artful
writing.

Repetition- The
return of a word, phrase, stanza form, or effect in any form of literature. Repetition
is an effective literary device that may bring comfort, suggest order, or add special
meaning to a piece of
literature

METONYMY: Using a
vaguely suggestive, physical object to embody a more general idea. The term
metonym also applies to the object
itself used to suggest that more general idea. Some examples of metonymy are using the
metonym crown in reference to royalty or the entire royal family,
or stating "the pen is mightier than the
sword" to suggest that the power of education and writing is more
potent for changing the world than military force.

Here's
one I can't be sure of because of how it has been identified on two different sites:
  The quote about the guillotine is
either...

MEIOSIS:
Understatement, the opposite of exaggeration: "I was somewhat
worried when the psychopath ran toward me with a
chainsaw."

OR

PARADOX
(also called oxymoron): Using contradiction in a manner that oddly makes sense on a
deeper level. Common paradoxes seem to reveal a deeper truth through their
contradictions, such as noting that "without laws, we can have no freedom." Someone even
mentioned oxymoron, but I can't be sure.

"A
little rule / a little sway..." is a kind of verse: called either a rhyme
or rhyming verse; it's a poem.

Hope these definitions are a
help.
