Sažetak The article discusses the literary and philological work of the priest Gašpar Glavanić, Burgenland Croat from Western Hungary, who lived from 1833 to 1872. In that period, opposing linguistic trends evolved : some philologists advocated a rapid and resolute adaptation to the literary language of Croatia, while others favoured the independent West-Hungarian variant, i. e. further development of Burgenland Croatian.
Alone and in cooperation with others, G. Glavanić published books in Hungarian orthography (e. g. 'Kerstianszko-Katolicsanszki Kalendar'), and later in Gaj's spelling (e. g. 'Početnica and Evangjelja, epistole i Štenja'). He also published 'Perva štanka' with a chapter dedicated to language instruction (“Podučavanje u jeziku”), which is considered to be the first published grammar for West-Hungarian Croats. Continuing his culturological and philological work, G. Glavanić wrote his 'Zabavno-poucsni Razgovor o hervackom pravopiszu', in which he resolutely and sharply opposed the conservatives who defended the old linguistic form.
Glavanić also wrote poems on the problems of village and town (e. g. “Srićan seljak”), on nationality (“Sarić i Cvilko”), etc. Due to all these activities, G. Glavanić can be considered a major promoter of Croatian culture in Western Hungary who provided an organic link in the development of linguistic studies between Matijaš Laab, Mihovil Naković and Mate Meršić Miloradić, and gave an invaluable contribution to its development.
