The construction [X, you are/were Y], where X is a spatio-temporal addressee, is widely attested on Dutch social media. We investigated this construction in a Twitter corpus, and found that Twitter users use the construction to tell their audience about a current or recent experience at the location addressed, while at the same time evaluating said experience. Reference to this first-hand experience is not overtly expressed, yet it is an essential interpretive aspect of the construction. The grammatical components of the construction all contribute in their own way to this interpretation. Although the use of the vocative and the second person pronoun personify the spatio-temporal addressee to a certain degree, the addressee's spatio-temporal characteristics remain crucial, as they provide the background for the reported experience. It is noticeable that particular instances of the construction, which would be blatantly ungrammatical in other contexts, are now acceptable in virtue of these spatio-temporal characteristics of the fictive addressee. This reveals the flexibility of grammar, as it shows how grammar can adapt to the possibilities and limitations of social media use, and make otherwise ungrammatical utterances, such as ‘you are raining’, fully comprehensible.

结构[ X，您是Y ]，其中X是时空收件人，在荷兰社交媒体上得到了广泛证明。我们在Twitter语料库中研究了此构造，发现Twitter用户使用该构造向听众讲述了所针对位置的当前或最近体验，同时评估了这些体验。关于这种第一手经验的参考文献并未公开表达，但这是该结构必不可少的解释方面。结构的语法组成部分都以自己的方式为这种解释做出了贡献。尽管使用称呼和第二人称代词在一定程度上体现了时空收件人，但收件人的时空特征仍然至关重要，因为它们为所报道的经历提供了背景。值得注意的是，由于虚构收件人的这些时空特征，现在可以接受在其他情况下公然不合语法的特定构造实例。这揭示了语法的灵活性，因为它显示了语法如何适应社交媒体使用的可能性和局限性，并且使其他诸如“你在下雨”之类的不合语法的话语完全可以理解。
