Based on the re-analysis of the evidence this paper demonstrates that a variety of Celtic was indeed spoken in Pannonia at least until the end of the 2nd c. AD. It also argues that most of the proposals regarding the influence of Celtic on Pannonian Latin cannot be upheld, because there were no demonstrable Celtic features that could have triggered such a change. The remaining cases are attested outside of the Celtic speaking areas too, and thus Celtic could at best have reinforced these changes. Only the sound change a > e might be attributed to Celtic influence. [ABSTRACT FROM AUTHOR]
