This paper presents an articulatory characterisation of the phoneme /s/ in northern peninsular Spanish, based on the analysis of a series of magnetic resonance images (MRI), in 2D and 3D. The set of articulatory parameters used in the analysis has proven useful for the description of Basque sibilants (Iribar et al., 2020, 2022, 2024). Three different models of /s/ production are identified and described: apical alveolodental, laminar alveolar and laminar alveolodental; only the first of these models corresponds to the traditional description of the so-called northern ese norteña. The shape of the articulatory canal, which does not seem to be related to the articulatory models, is also studied.
