In this paper a comparison was made between the ancient Poljica records and today's Poljica speech. For the analysis of the old Poljica records, a collection of folk songs was used, called the National Song of Donji Dolac, Srijane and Biska (Poljica), more precisely the folk song by Manda Strujić, and the transcribed record of a story from a native speaker from the area of Upper Poljica, Marija Prelas. On the other hand, a transcribed story about Christmas, also by a native speaker from the Upper Poljica region, Dražimir (Draško) Mladina, was used for analysis of today's Poljica speech. After the conducted dialectological analysis of the mentioned songs and records, it was established that the Poljica idiom has been preserved to this day. Poljica is considered a Dalmatian treasure, so many Poljica natives try to preserve it. With the arrival of new generations, the Poljica idiom is slowly approaching the standard. The dialectic traits found in the old Poljica records have also been preserved in today's Poljica speech. Thus, in the aforementioned records and in today's speech, the phenomenon of Adriatism is noticed, i.e. the transition of the -m to -n. Ikavian yat reflex is also in use in today's speech mode. Today, progressive assimilation is regularly carried out, as can be seen in the examples of usika (usjekao – to cut), iša (išao – to go), reka (rekao – to say) osta (ostao – to stay). Indicative pronouns are recorded in the form of ovi. The occurrence of dropping one of the two consonants in the consonant sequence is also noted, for example, ko’ko (koliko – how much/many), ‘vako (ovako – like this). Likewise, instead of the phoneme h, we notice the phoneme v, eg. kuhat – kuvat (to cook). And in today's Poljica idiom, the occurrence of the startup sequences -an, and also -in is noticed. Also, following the analysis of today's Poljica speech based on the analysed transcribed story, the preservation of Chakavian has also been recorded.
