There are certain kinds of information that can be conveyed more readily and clearly by pictures than by descriptions and explanations. This dictionary identifies over 29,000 objects by means of numbered illustrations, offering at a glance their Spanish and English terms. The edition has been revised and updated to reflect the most up-to-date changes in technology, science and medicine, industry and commerce, and to offer even wider coverage of all major fields of reference, including the arts and entertainment, recreation and sport, flora and fauna and typical situations in domestic and everyday life. Every vocabularly item is indexed in Spanish and English so that the dictionary can be used in both directions. The subjects are organized thematically enabling the user to grasp the entire vocabulary relevant to a given situation or context.
