Using map task data, this paper investigates the intonation of polar questions in North American (heritage) Icelandic, and compares it to the intonation of polar questions in Icelandic as spoken in Iceland and in North American English as spoken in Manitoba, Canada. The results show that intonational features typical of Icelandic polar questions are present to a considerable extent in heritage Icelandic. Furthermore, intonational features typical of North American English polar questions can frequently be observed in heritage Icelandic, too. In addition, there is a tendency for intonational features typical of Icelandic polar questions to show up in North American English polar questions produced by speakers of heritage Icelandic more often than in North American English polar questions produced by speakers without Icelandic heritage. Focusing on intonation, the present study adds to the evidence for (bidirectional) prosodic interference between a heritage language (here moribund Icelandic) and the dominant language (here North American English).*

北美（“遗产”）冰岛语中极地问题的语调

使用地图任务数据，本文研究了北美（遗产）冰岛语中极地问题的语调，并将其与冰岛语中冰岛语和加拿大马尼托巴省使用的北美英语中的极地问题语调进行了比较。结果表明，冰岛语极地问题的典型语调特征在很大程度上存在于冰岛语遗产中。此外，在传统冰岛语中也经常可以观察到北美英语极地问题的典型语调特征。此外，冰岛极地问题的典型语调特征倾向于在北美英语极地问题中出现，由具有冰岛血统的人提出的问题比在没有冰岛血统的人提出的北美英语极地问题中出现的频率更高。*
