From vulgar insults to religious oaths, colloquialisms to clichés, the personality and passion of a language can be found in its slang. Spanish is no exception, as the McGraw-Hill Diccionario del Argot makes clear. This monolingual Spanish dictionary provides the most authoritative reference to all aspects of non-standard Spanish, with more than 12,000 entries supported by 20,000 citations. The broad range of sources, from literature to newspapers and TV, reflects the full spectrum of contemporary usage in Spain. For scope and depth as well as bibliographic reference, this is an essential language tool for libraries, advanced-level students, teachers, scholars, and lexicographers.
