Inevitably we stumble upon Latin words and abbreviations in writings (especially of an older generation). Often I simply ignore them, but they are becoming more important when I really need to understand what the author is communicating in a footnote. So, I have compiled a list of Latinisms that you may find in monographs and especially in older reference works that rely on keeping words short (like Liddell-Scott or BDAG). If you come across others that are frequently occuring and would be of aid to the biblical-academic community, please feel free to let me know so I can add it/them. BEWARE: Many of these are from Wikipedia! I have tried to double check many of them.
