Proper noun
Ijekavian
A dialect, group of dialects or dialect continuum of Serbo-Croatian spoken through most of Croatia, Bosnia and Montenegro and parts of Serbia and distinguished by reflecting the Common Slavic jat (Old Cyrillic: ѣ, Glagolitic: ⱑ, Latin transcription /ě/) sound as disyllabic (triphonemic) /ije/ or diphthongal /je/ sequence.
For verbs that had -ěti in their infinitive, the past participle ending -ěl evolved into -io in Ijekavian Neoštokavian. Source: Internet
The prefix prě- ("trans-, over-") when long became pre- in eastern Ijekavian dialects but to prije- in western dialects; in Ikavian pronunciation, it also evolved into pre- or prije- due to potential ambiguity with pri- ("approach, come close to"). Source: Internet
