In everyday use, most English speakers use "poetry" or "poems" to refer to "lyric poetry"—normally short verbal expressions of impressions or feelings; e. g., "I Wander'd Lonely As a Cloud," "Stopping by Woods on a Snowy Evening," or "My Love is Like a Red, Red Rose."
But in academic or old-fashioned uses, "poetry" can refer more broadly to all the genres we now call literature: lyric, drama, epic, even the novel, or to sub-genres of verse like narrative poems or the dramatic monologue.
