This website allows you to quickly and easily search more than 100 million words in more than 20,000 Spanish texts from the 1200s to the 1900s. The interface allows you to search for exact words or phrases, wildcards, lemmas, part of speech, or any combinations of these.  You can search for surrounding words (collocates) within a ten-word window (e.g. all nouns somewhere near cadena, all adjectives near mujer, or all nouns near girar). 

The corpus also allows you to easily limit searches by frequency and compare the frequency of words, phrases, and grammatical constructions, in at least two main ways:

• By register: comparisons between spoken, fiction, newspaper, and academic

• By historical period: compare different centuries from the 1200s to the 1900s

You can also easily carry out semantically-based queries of the corpus. For example, you can compare and contrast the collocates of two related words, to determine the difference in meaning between these words.  You can find the frequency and distribution of synonyms for nearly 30,000 words and also compare their  frequency in different registers and historical periods, and use these word lists as part of other queries. Finally, you can easily create your own lists of semantically-related words, and then use them directly as part of the query.

Please feel free to take a five minute guided tour, which will show the major features of the corpus.  A simple click for each query will automatically fill in the form for you, search through the 100 million words of text, and then display the results.  This corpus of Spanish is fast, free, easy to use, and we believe that it offers important features not found in any other interface to a large corpus of Spanish.
