noun libretto

• text — the main body of matter in a manuscript, book, newspaper, etc., as distinguished from notes, appendixes, headings, illustrations, etc.
• theme — a subject of discourse, discussion, meditation, or composition; topic: The need for world peace was the theme of the meeting.
• verse — (not in technical use) a stanza.
• book — A book is a number of pieces of paper, usually with words printed on them, which are fastened together and fixed inside a cover of stronger paper or cardboard. Books contain information, stories, or poetry, for example.
• words — a unit of language, consisting of one or more spoken sounds or their written representation, that functions as a principal carrier of meaning. Words are composed of one or more morphemes and are either the smallest units susceptible of independent use or consist of two or three such units combined under certain linking conditions, as with the loss of primary accent that distinguishes black·bird· from black· bird·. Words are usually separated by spaces in writing, and are distinguished phonologically, as by accent, in many languages.
