The present study examines the fate of the neoclassical combining form pseudo- in eight European languages, belonging to Germanic (Danish, Dutch, English, German and Swedish) and Romance (French, Italian, Spanish). In order to gain a better understanding of the synchronic morphological behaviour and productivity of pseudo- words in these languages, we carry out a cross-linguistic corpus analysis and compare the morphological and distributional properties of pseudo-. We also analyse its debonding behaviour and categorical flexibility in the set of languages and correlate this property with its productivity. The results of the corpus study are discussed against the typological background of the so-called Germanic and Romance Sandwiches.
