The Mexican Dictionary of Spanish is the result of a set of investigations of the vocabulary used in the Mexican Republic since 1921. The investigations have been carried out since 1973 at the Center for Linguistic and Literary Studies of El Colegio de México.
The Mexican Dictionary of Spanish is a comprehensive dictionary of Spanish in its Mexican variety, prepared on the basis of an extensive study of the Corpus of contemporary Mexican Spanish (1921-1974) and a set of data after that last date to the present.
It is an original, descriptive work, made with exclusively linguistic criteria. All the vocabulary it includes has been used or is used in Mexico, at least since 1921.
When you open the dictionary, the space to search for a word appears at the top.
Below is a section called Word Lottery, which randomly chooses one of the words contained in the dictionary. This Lottery seeks to arouse greater interest in the content of the dictionary. Each time this screen opens, the Lottery will select a new word. The moment the answer to the search appears, the Lottery disappears.
A drop-down list appears in the upper left-hand side of the screen where the sections About DEM, DEM Supports, and Videos can be viewed.
Spelling, stress, and punctuation rules are illustrated in DEM Supports. There is also an explanation of the use of each of the verb tenses. Tabs are provided on prefixes and suffixes. In addition, you can find writing lists of names of the Mexican Republic, of the Spanish-American countries and of the numbers.
