García Fuentes, Araceli2011-04-012011-04-0120081886-2438https://riunet.upv.es/handle/10251/10641[EN] This paper is based on a research project by the same author; in which the acquisition of the English negation system is investigated. This is a preliminary account and it is corpus-based. Two learner corpora were used: the International Corpus of Learner English (ICLE) Spanish subcorpus and the Santiago University Learner of English Corpus (SULEC). The former is a sample corpus -it is finished- and it contains written argumentative essays of Spanish speakers. The latter contains both spoken and written data -oral interviews and argumentative texts- and it is a monitor corpus; new data are continuously being added. The Spanish subcorpus of ICLE contains over 125.000 words; whereas SULEC contained over 350.000 words at the moment of the research. A native English corpus was also used in order to contrast the learner and the native use of English negation.Reserva de todos los derechosCorpus linguistics (CL)Learner corpusForeign Language Learning (FLL)Second Language Acquisition (SLA)English as a Foreign Language (EFL)Artículo2011-03-3110.4995/rlyla.2008.689Abierto1886-6298
