librum

Librum is the accusative singular form of the Latin noun liber, meaning "book." In Classical Latin, liber can refer to a book, a scroll, or a bundle of writings, and librum serves as the direct object with verbs such as legere (to read), scribere (to write), or tenere (to hold). The word appears in many Latin texts from the Republic and Imperial periods, though liber is more common when speaking of books in general. Latin has no indefinite article, so librum functions without an article.

Morphology: Librum is part of the second declension masculine nouns. Its principal parts are liber, librī, librō, librum, librō. The plural forms are librī (nominative), librōrum (genitive), librīs (dative/ablative), librōs (accusative).

Usage and examples: Typical phrases include librum legō "I read a book," librum tenēre "to hold a book," and librum dāre or emit librum "to give/buy a book." In contexts, librum may be specified as a particular book, while liber can refer more broadly to a work or to books in general.

Modern relevance: The Latin noun liber is the etymological source of many terms in modern languages related to books and repositories, such as library (via Latin librarium and French librairie), and is studied today in Latin grammar and philology. Librum itself remains a form used primarily in texts written in Latin or in discussions about Latin grammar.
