The present paper describes the main discursive uses of creo , a performative form of doxastic verb creer , in oral Spanish interaction, specifically those in which the verbal form shows attenuation or intensification. To that end, this paper performs a thorough analysis of creo instances across conversational corpora ( COGILA, COJEM, Val.Es.Co., Val.Es.Co. 2.0 ) and parliamentary debates corpora ( Congreso de los Diputados, Les Corts Valencianes ), with a combined 700 000 words collated as the sample. A preliminary qualitative and quantitative investigation was carried out in which the goals were twofold: First, to isolate the features of each Concrete Interactive Context ( CIC , Briz y Albelda, 2013) of creo in wich the doxastic verbal form appears and to identify which features favor its use (namely, register, level of dialogicity, and specific genre traits, Soler, 2019). Second, to determine what argumentative, face, or discursive factors influence the development of frequent pragmatic functions (Soler, 2018). This work finds that creo , although defined as a polyfunctional form (Simon-Vandenbergen, 2000; Gachet, 2009: Mullan, 2010), exhibits a set of three pragmatic values that affects, in different ways, the interactants’ face: affiliation or reinforcement of relations with other/-s - neutrality - de-responsibility.
