The prescriptive infinitive can be found in the North Germanic languages, is very old, and yet is largely unnoticed and undescribed. It is used in a very limited pragmatic context of a pleasant atmosphere by adults towards very young children, or towards pets or (more rarely) adults. It has a set of syntactic properties that distinguishes it from the imperative: Negation is pre-verbal, subjects are pre-verbal, subjects are third person and are only expressed by lexical DPs, not personal pronouns. It can be found in modern child language corpora, but probably originated beforead500. The paper is largely descriptive, but some theoretical solutions to the puzzles of this construction are proposed.

现代北日耳曼语中的规定不定式：面向儿童的语言中的一种古老现象

规定不定式可以在北日耳曼语中找到，非常古老，但在很大程度上没有被注意到和描述。它用于成人对非常年幼的孩子或宠物或（更罕见的）成人的愉快气氛的非常有限的实用语境中。它有一组句法属性，将它与祈使句区分开来：否定是前动词，主语是前动词，主语是第三人称，并且仅由词汇 DPs 表达，而不是人称代词。它可以在现代儿童语言语料库中找到，但可能起源于以前广告500. 这篇论文主要是描述性的，但提出了一些解决这一结构难题的理论解决方案。
