Obrađuju se refleksi praslavenskoga e u hrvatskim organskim idiomima u povijesnoj perspektivi i u suvremenosti. U tom je smislu naročito istaknuta pri- mamost refleksa jata u štokavštini odnosno njihova sekundamost. Primamost bi se odnosila na izravan prijelaz zatvorenoga e u i ili u e, dok bi sekundamost značila dobivanje i ili e od diftonga. Ukratko su prikazani i refleksi jata u nehrvatskim govorima središnjega južnoslavenskoga dijasistema, osobito gdje se radi o hrvatskom stanovništvu.The paper analyzes the reflexes of Proto-Slavic jat in organic Croatian idioms, both from an in historic perspective and in the present time. Particular attention is given to the primary and secondary importance of the jat’ reflexes in Stoka- vian. The primary reflex refers to the direct shift of closed e to i or e, while the secondary reflex describes the i or e derived from a diphthong. A short survery of the jat reflexes in non-Croatian speeches is also given. It has been shown that among Stokavian Croats speaking ijekavian and ikavian one can find scakavian and stakavian, as well as neo-stokavian and non-neo-stokavian speaking groups, while it is relevant for ekavian speaking stokavians only if we also take into account the non-Croatian speeches among the idioms of the central South-Slavic language diasystem. That is exactly the situation we would expect for the isoglosses, because they can be combined with any development possibilities. Cakavian and kajkavian, as well as stokavian confirm that conclusion
