Monografija združuje 12 prispevkov, v katerih je slovensko in drugo slovansko besedje predstavljeno v novi ali izboljšani interpretaciji na pomenski in/ali formalni ravni, zato dopolnjujejo vedenje o zgodovini, predzgodovini in etimološkem nastanku slovenskega in slovanskega leksikona.

V delu je analizirano naslednje besedje: sln. dial. seber ‘revež, nebogljenec’ (Zatolmin); sln. oča in oče; sln. dial., hrv. dial. boškarin ‘istrsko avtohtono govedo’; sln., hrv. hidronim Dragonja; sln. mirodilnica ‘drogerija’; sln. dial. mel/mjel/njel/gnjel … ‘vrsta hrasta’, hrv. dial. mjev/mnel … ‘isto’; sln. dial. durla ‘polšja samica’; sln., hrv. kuzla ‘psica’; sln. dial. koka ‘kača’; hrv. dial. švenac ‘uš’, blg. dial. švenec ‘isto’; psl. *pyriti ‘delati ogenj’, *puriti ‘isto’.

Zadnji prispevek je posvečen vprašanju jezikovnega razvoja, ki ga zaznamujeta tako jezikovna sistemskost in zato jezikoslovna predvidljivost kot tudi jezikovna nesistemskost in zato jezikoslovna nepredvidljivost.

The work features twelve contributions in which Slovenian and other Slavic vocabulary is presented in a new or improved interpretation at the semantic and/or formal level, thereby adding to the knowledge of the history, prehistory, and etymological formation of the Slovenian and Slavic lexicon.

In order of appearance the analysed words are the following: Slov. dial. seber ‘poor man, poor thing’ (Zatolmin); Slov. oča ‘father’, oče ‘idem’; Slov. dial., Cro. dial. boškarin ‘breed of cattle native to Istria’; Slov., Cro. hydronym Dragonja; Slov. mirodilnica ‘drugstore’; Slov. dial. mel/mjel/njel/gnjel … ‘type of oak’, and Cro. dial. mjev/mnel … ‘idem’; Slov. dial. durla ‘female dormouse’; Slov., Cro. kuzla ‘bitch, female dog’; Slov. dial. koka ‘snake’; Cro. dial. švenac ‘louse’, and Bulg. dial. švenec ‘idem’; PSl. *pyriti ‘to make a fire’, *puriti ‘idem’.

The last contribution is dedicated to the question of linguistic development, which is characterized by linguistic systematicity and therefore linguistic predictability, and also by linguistic non-systematicity and therefore linguistic unpredictability.
