This paper deals with the diversity of temporal and spatial phrases – mainly those headed by prepositions or preposition-like connectives – that convey locating information or involve mere temporal/spatial reference. It shows that the different subclasses are quite heterogene ous in Portuguese, and exhibit interesting, syntactically complex, patterns. A certain degree of instability in their use, likely indicative of linguistic change (mainly in Standard European Portuguese), is illustrated through the use of corpora examples. English data is often used for comparison. The formal framework underlying the linguistic analyses is Discourse Representation Theory (cf. Kamp & Reyle 1993).

葡萄牙语时空短语的子类–位置与内容参考

本文探讨了时空短语的多样性（主要是那些以介词或类似介词的连词为首的短语），这些短语传达了定位信息或仅涉及时空参考。它显示了不同的子类在葡萄牙语中是非常不同的，并且表现出有趣的，语法复杂的模式。通过使用语料库示例说明了它们使用中的一定程度的不稳定，可能表示语言发生了变化（主要是标准的欧洲葡萄牙语）。英文数据通常用于比较。语言分析的形式框架是话语表征理论（参见Kamp＆Reyle 1993）。
