According to Wikipedia,
Romanian has [...] the glottal fricative /h/.
You can hear it, for instance, in the Romanian word arhaic.
This cannot be of Latin origin because, as explained in the book La filologia romanza by Pietro G. Beltrami, Latin /h/ was lost everywhere in the Romance domain and has left no trace in the Romance languages. So I suppose that this /h/ was acquired at a certain point in the history of Romanian. Can someone explain this? Is that to be attributed to the Slavic superstratum?
hin Albanian and its omnipresence (and naturalness) in Romanian shows the strong Slavic lexical impact on Romanian compared to that impact on Albanian - but it doesn't show that the impact of the "Albanian-relative" on Romanian was weak. And it is consistent with the idea that Slavic invasions is what separated the Romanian and Albanian linguistic areas. – cipricus Sep 26 '22 at 09:21
