The Bachelor of Laws (abbreviated LL.B., LL. B., LLB, or rarely, Ll.B., but never L.L.B.) is an undergraduate, or bachelor, degree in law (or a first professional degree in law, depending on jurisdiction) originating in England and offered in most common law countries as the primary law degree.[1] In English-speaking Canada it is sometimes referred to as a post-graduate degree because previous university education is usually required for admission. The "LL." of the abbreviation for the degree is from the genitive plural legum (of lex, law). Creating an abbreviations for a plural, especially from Latin, is often done by doubling the first letts (e.g. "pp" for "pages"), thus "LL.B." stands for Legum Baccalaureus in Latin. It is sometimes erroneously called "Bachelor of Legal Letters" to account for the double "L".
