This paper investigates how neological intuition (NI), i.e., the metalinguistic ability to evaluate lexical novelty, is influenced by the linguistic properties of novel words. We focus on two properties: (i) formal novelty, depending on whether neologisms result from a morphological operation or are already existing forms that take on new meanings, and (ii) lexical regularity, depending on whether neologisms are created through regular linguistic processes or not. We hypothesize that morphological neologisms are more salient than semantic ones, and that irregular neologisms are more salient than regular ones. We designed a behavioral experiment to test these hypotheses with French native speakers, measuring detection rates and response times for various types of neologisms. The results support our main hypotheses, additionally showing that lexical regularity is a stronger predictor than formal novelty, and that an interaction effect exists between the two factors.

本文研究了新词的语言特性如何影响神经直觉（NI），即评估词汇新颖性的元语言能力。我们关注两个特性：（i）形式上的新颖性，取决于新词是否是形态学操作产生的，还是已经具有新含义的现有形式；（ii）词汇规律性，取决于新词是通过常规的语言过程还是通过新的语言过程创建的不是。我们假设形态新词比语义新词更显着，不规则新词比常规新词更显着。我们设计了一个行为实验，使用法语为母语的人来测试这些假设，并测量各种类型新词的检测率和响应时间。结果支持我们的主要假设，
