Godine 1964. Mate Hraste potaknut referatom P. Ivića pod naslovom O klasifikaciji srpskohrvatskih dijalekata održanim na “kongresu jugoslavenskih slavista” u Ohridu 1963. istraživao je govore jugozapadne Istre s ciljem “da utvrdi koliko je točno određivanje štokavskoga područja u Istri i koliko se u Istri uopće govori štokavski” (Hraste 1964: 6). U tom je istraživanju obišao 22 dijalektološka punkta u kojima je provjeravao Ivićevih “14 razlika između štokavskog i čakavskog” narječja te pridodao i niz jezičnih značajki koje potvrđuju pripadnost jugozapadnih istarskih govora čakavskome sustavu. Rezultate svojih istraživanja objavio je u raspravi Govori jugozapadne Istre. Ta je rasprava i danas polazište za istraživanje još uvijek nedovoljno poznatih čakavskih govora jugozapadne Istre. U ovome smo radu prikazali novija istraživanja jugozapadnih istarskih štakavsko-čakavskih govora koja se temelje na Hrastinu istraživanju.In 1964, encouraged by Pavle Ivić’s paper “On the Classification of Serbo-Croatian Dialects” presented at the congress of Yugoslav Slavists in Ohrid (1963), Mate Hraste undertook a study of the southwest Istrian dialect in order “to determine how accurately the Štokavian area in Istria had been delineated and how much Štokavian is spoken in Istria at all” (Hraste 1964: 6). In the course of his research he visited 22 dialectological points to check “the 14 differences between Štokavian and Čakavian” dialects, as identified by Ivić, and added a range of linguistic features supporting the idea of the southwest Istrian dialect as part of the Čakavian group. He published the results of his research in a paper entitled “The Subdialects of Southwest Istria.” Even today this paper is the starting point for research into the still insufficiently known Čakavian subdialects in the southwest of Istria. The current paper, based on Hraste’s pioneering work, presents more recent research into the southwest Istrian Štokavian dialect
