Abstract
Languages have been in contact since their existence. The Hungarian and Romanian languages have been so for at least 800 years. The present article aims at analysing the structural changes in the monosyllabic Hungarian loanwords in Romanian. After the theoretical introduction, I discuss the phonological status of the /j/ sound, which is very important in this kind of investigations. After that, I present the syllable structure types of these monosyllabic Hungarian etymons and I present, as well, the changing schemes of their structures in the borrowing. The study concludes that the most affected parts of the syllables are the nucleus and the coda.
