In this paper, we introduce the constructional morphology model, summarizing different works by Booij (2005, 2007, 2010). We build upon this model a better comprehension about morphological phenomena in Portuguese. As a result, we not only propose a new approach to word formation, but we improve the original model, adding new theoretical tools. We focus, in this work, especially: (a) the so-called combining forms(GONCALVES, 2012), as -nejo ('pagonejo', 'sextaneja') and caipi- ('caipi-fruta', 'caipi-saquê'), that create morphological patterns similar to those of affixes; (b) the "jumping steps" in word- formation (SANDMANN, 1994), observed, for example, in lexical constructions like 'desratizar' and 'churrascabilidade', with simultaneous concatenation of two affixes; and (c) derivational general patterns (BASILIO, 1980), whereby two morphological constructions interact, because they presuppose each other, such as X-ista and X-ismo, in data like 'marxismo' / 'marxista' and 'budismo' / 'budista'.
