From N to particle
The paper addresses the distribution of preposition-drop with the noun <i>casa</i> ‘home’ in the spatial adpositions of some Northern Italian varieties. It is shown that in these varieties P-less <i>home</i> behaves syntactically as a locative adverb, which under specific circumstances, becomes a <i>particle</i>. It is suggested that P-less <i>home</i> is not a special noun but a proper member of the category P generated in a specific projection in the fine-grained PP (Cinque 2010), hosting <i>viewpoint</i> modifiers of the silent head PLACE. The adverb vs. particle nature of P-less <i>home</i> derives from motivated movements inside and outside the PP triggered by a directional context. The same analysis is extended to Modern (and Old) English <i>home</i>.
