The SIGNUM lexicon is based on a core of over 115,000 terms, which includes a good part of the local terms used in Spanish-speaking countries and technical vocabulary used in many areas of science and trade. It contains new terms that are currently used in publications but do not appear in many dictionaries, as well as seldom used words found in specialized literature.

The 115,000 lemmas core is supplemented by the inflections of these words. It encompasses inflections for gender and number, as well as inflections for diminutives, augmentatives, superlatives and pejoratives; all verb conjugations; the most commonly used enclitics; and also derivative morphemes, such as "-mente, -ismo, super-, semi-, pre-, pos-" among others. Taking all these inflections into account, the lexicon comprises some 5,000,000 words.

Each term of the lexicon includes dozens of attributes to provide morphological, grammatical, semantical and other types of data, such as a frequency index that tells us how common or rare the word is.

Two application areas of the SIGNUM lexicon are worth pointing out: our linguistic engines draw on the lexicon in a very efficient manner to perform their processing; and this lexicon is the basis from which word lists, consisting of specific types of lemmas and inflected forms, are generated according to the specific requirements of an application or user in need of a high-quality lexicon.
