A popular legend of folklorists tells about the beginning of the town that the land on which the town of Ungheni is located today belonged once to a certain boyar Vasile Lupu from the village of Untesti. This, he said, would have had a beautiful daughter who was one day stolen by the Turks. A hurry was organized immediately and, at the place where he was released, the boyar set up an inn. During the excavation of the foundation, sheep hooves, called "nails" were discovered, hence the name - "Han's Nails". In time, the place became a village, and its name turned into Ungheni [1].
The original name of the village was Unghiul. Thus it was called between the years 1462-1587 [2]. This toponymy originates in the geographic aspect of the territory on which the settlement was originally constituted, the Prut River forming a perfect angle here by a sharp curve [3]. Unlike other towns, Ungheni had no other names, which determines us to find the historical and demographic and historical continuity of the locality.
So, the original name with which the registered village appears is Angle. Geographically, the source finds it "below Filifoe on Jijia ... with two dams that are between the Prut and between Jijia." From the point of view of the actual geographical and historical reality, the act generates a slight confusion, because the location of the settlement is on the right side of the Prut, bearing the same name Ungheni (Romania), and the name with which it appears mentioned today is no longer present, The fact that the issue of the identity of the Angle from 1462 with the present Ungheniya (Appendix 5) results.
The historian Gh. Ghibanescu, who first published the document in 1907, localized Unghiul village in full knowledge of the matter, the researcher being informed, in addition to the prominent manuscript, and the living testimony of his owner at the time of publishing: Mihai Buznea, the owner of Ungheni at the beginning of the 20th century [4].
The same is true of the historian Ioan Bogdan in 1913, when he published the document of Stephen the Great in his monumental collection of medieval Moldavian acts [5].
Mihai Costăchescu, a learned paleographer and tireless publisher of old chrisoave, pleaded in 1931 for the same geographic and toponymic identity of Ungheni with Angle in 1462.
In one of the earliest studies dedicated to the population of Iaşi County in the medieval age (elaborated in 1948), researcher Letiţia Lazarescu identifies the Angle of the document from 1462 with "The current Ungheni on both sides of the Prut".
Broadly speaking, most researchers who have leaned on the issue in question have similar opinions. However, over time, there have been different views. One of them is the opinion of Chisinau philologist A. Eremia. The distinguished scholar is right in saying that the toponym Ungheni is drawn from Angle to the Prut and that it is of geographic origin. Being a tributary of the political realities existing at the time of writing his study, A. Eremia overlooked the uranium of Stephen the Great in 1462, considering that the first documentary mention of Bessarabian Ungheni is in an act from 1587.
The same mistake is committed by researchers D. Haidarl and Vl. Nicu. The latter in general claims that the name of Ungheni has nothing to do with Unghiul in 1462 and that the origin of its appearance was the old town of Ţuţora, which is why the first documentary mention of the first one - 1454 is quite wrong.
Therefore, most researchers who studied the document on August 20, 1462, have no doubt that the "Angle Below the Filipe on Jijia" is the origin of the current dual settlements on the Prut: Ungheni village (Romania) and Ungheni city Moldova).
