The book entitled New insights into the mental lexicon provides significant insights into meaning creation by unfolding a wide-ranging array of current preoccupations in cognitive linguistics, psycholinguistics, corpus research and media studies. Notably, the present volume pursues the subtle issues of word or concept meanings, of the argument over the likely interface between meaning fixedness and fuzziness or fluidity, of the (im)possibility to deal with these ‘slippery customers’ (Labov 1973), and the ‘vague boundaries and fuzzy edges’ (Lakoff 1972) of natural language concepts. It is organised into three main parts, the first dedicated to the functioning and processing of meaning in both mother tongue (Romanian) and foreign language (English), the second concentrates on meaning creation in various discourses (cultural, political, business journalese, social media), whereas the third focuses on the subject of meaning construction in literary productions and film adaptations. As for the research methodology, the book is based on a large mixture of frameworks: Pragglezaj method (2007), MIPVU technique (2010), Charteris- Black’s (2004) critical metaphor analysis framework, Alice Deignan’s corpus-based metaphor analysis (2005), Halliday and Hasan’s Systemic Functional Linguistics (SFL) framework (1989), Forceville’s multimodal metaphor analysis theory (2009), parallel text analysis, Isabela and Norman Fairclough’s political discourse analysis (2012). Qualitative as well as quantitative analysis of data was carried out, coupled with semi-automatic treatment of text, using LancsBox and ConcApp concordancing software. The mental lexicon is mainly tackled from a cognitive-linguistic perspective rather than from a psycholinguistic one, with a conspicuous focus on abstract features of the lexicon, applying linguistic grammars and dictionaries, lexical databases (WordNet) and word categorisation in corpora. It is also worth mentioning that experimental data was formed from elicited behaviour of Romanian learners of English. Last but not least, limitations are imposed by the scope of research, carried out within a limited time frame and involving the construction of a small size of corpora.
