From 11:00PM PDT on Friday, July 1 until 5:00AM PDT on Saturday, July 2, the Shmoop engineering elves will be making tweaks and improvements to the site. That means Shmoop will be unavailable for use during that time. Thanks for your patience!
These cute little buggers are tiny stanzas. So tiny, in fact, that they only include two lines. Sometimes they rhyme, sometimes they don't. Sometimes they're written in meter (as in heroic couplets), sometimes they're not.
Bottom line? If you see a stanza that's two lines long, it's a couplet.
