Using the variationist comparative method, the status of ambiguous lone Spanishorigin nouns in Catalan discourse is determined by analyzing their distribution and conditioning and by comparing them to their counterparts in unmixed Spanish or in multiple-word code-switches. Some areas of the nominal grammar have been selected for contrastive purposes (determination, complementation, gender, number) because they represent sites of coincidence as well as conflict between the two languages in contact, Spanish and Catalan. The main conclusion of this research is that Spanish-origin nouns in an otherwise Catalan context present grammatical variability similar to that of Catalan nouns, and that they behave differently from Spanish nouns in a monolingual context. In short, the grammar of these nouns is Catalan, and their categorial status is that of loanwords and not that of code-switches.

In this study the use of "well" as a discourse marker is analysed in sixteen episodes of a television series and in two English language textbooks to illustrate what communicative language teaching can get from work on discourse analysis. Results of the analysis show that the meaning ofwellas a mainly interactive device signalling acceptance due to modification is present both in television series and in textbooks. However, the analysis also shows an absence of inductive and language awareness approaches to focus learners’ attention on the interactive features of “well” as a discourse marker. Further research is needed in different languages to understand the meaning and use of discourse markers and the implications of these analyses for language teaching.
