Poem, rhyme, stanza, foot
The other day, I was driving home from work and half-listening to NPR when I heard the speaker mention something about a "poetry ontology." (In information science, an ontology is a map of relationships between major concepts in a subject area.)
"How interesting!" I thought, "Poetry seems like an unlikely subject for an ontology, but that could be really fascinating."
And then I realized Andrei Codrescu's (who has a strong Romanian accent) was actually talking about a "poetry anthology."
(But I'm still thinking about poetry ontologies.)
