Studies of language contact in the Central Andes of Peru and Bolivia have focused strongly on the present-day contact situation between Quechua and Spanish, and the intricate and multilayered contact relationship between the Quechua and Aymara lineages. There are fewer studies of the influence of Quechua on minor non-Quechua languages of the Andes, and still fewer studies which, conversely, explore the influence of non-Quechua languages on Quechua. Focusing on the lexicon, this article explores the impact of the complex linguistic ecology of Northern Peru on the five Quechua varieties of that region—Lambayeque, Cajamarca, Chachapoyas, San Martín and Ancash Quechua. The study identifies lexical items that lack clear Quechua etymologies in the relevant varieties and carries out external comparisons of these items with the vocabulary of the non-Quechua languages of Northern Peru to identify possible sources. Results show that borrowing is mostly localized: that is, whereas influence from Amazonian lowland languages is almost exclusively found in the eastern varieties of Chachapoyas and San Martín, highland Quechua varieties have typically borrowed from neighboring highland languages.

秘鲁和玻利维亚中部安第斯山脉的语言接触研究主要集中在盖丘亚族和西班牙语之间的当今接触情况以及盖丘亚族和艾马拉族之间复杂而多层的接触关系。关于盖丘亚语对安第斯山脉次要非盖丘亚语影响的研究较少，相反，探索非盖丘亚语对盖丘亚语的影响的研究也较少。本文着眼于词典，探讨了秘鲁北部复杂的语言生态学对该地区的五个Quechua变种的影响-Lambayeque，Cajamarca，Chachapoyas，SanMartín和Ancash Quechua。该研究确定了在相关品种中缺乏清晰的盖丘亚语词源的词汇项目，并将这些项目与北秘鲁非克丘亚语的词汇进行了外部比较，以找出可能的来源。结果表明，借贷大部分是本地化的：也就是说，虽然亚马逊低地语言的影响几乎只出现在Chachapoyas和SanMartín的东部品种中，但高地Quechua品种却通常是从邻近的高地语言中借来的。
