‘Rhetoric, poetics and poetry’ explores these literary effects with examples. Poetry is closely allied to rhetoric — the study of the persuasive and expressive resources of language. Poetry is language that makes abundant use of figures of speech and language. In literary theory, a poem is both a structure made of words (a text) and an event (an act of the poet, an experience of the reader, an event in literary history). Genres are sets of conventions and expectations: knowing whether we are reading a detective story or a romance, a lyric poem or a tragedy, we look out for different things and make assumptions about what will be significant.
