The study presented in this paper aims to perform a comprehensive analysis of the use of phraseological units (PUs) in contemporary Spanish according to two different levels of oral language production: (a) spontaneous informal (on the basis of conversations uttered among the contestants of the Spanish version of the reality show Big Brother ), (b) spontaneous formal (on the basis of interviews performed on Spanish radio and TV programmes). The configuration of Spanish phraseology as it is used in formal and informal spontaneous oral language production will be investigated according to four variables: frequency distribution, typological distribution, stylistic distribution, and individual distribution. It will be shown that a) the more informal the discourse context, the higher the frequency of use of PUs, b) that idioms (and not routine formulae or proverbs ) are clearly dominant in both formal and informal oral contexts, c) that there are speakers in formal discourse contexts who often utter informal PUs, d) that vulgar vs. non-vulgar PUs – and not so much informal vs. non-informal PUs – is the main disagreement between formal and informal spontaneous oral contexts, and e) that using vulgar PUs more or less frequently would be a highly individual issue.

正式和非正式自发口语制作中的西班牙语措辞

本文提出的研究旨在根据两种不同的口头语言产生水平对当代西班牙语中的措词单位（PU）的使用进行全面分析：（a）自发非正式（基于参加者之间的交谈）西班牙版的真人秀节目《老大哥》，（b）自发正式的（基于对西班牙广播电视节目的采访）。将根据四个变量来研究用于正式和非正式自发口语生产中的西班牙语用语的配置：频率分布，类型分布，风格分布和个体分布。结果表明：a）话语语境越非正式，使用PU的频率就越高；
