Reconstructing Gothic, some say, involves a lot of extrapolation. Apart from Latin and Greek, there are not many sources of Gothic loanwords that are reasonably close to Gothic in place and time and that have a preserved corpus predating the Gothic. If there was, reconstruction would be based on interpolation which is more reliable than extrapolation. But there is Hebrew. Here are a few passages involving Gothic and Hebrew “ak” – a contrasting adverb or conjunctive, and the Gothic word for house “gards” compared with the Hebrew word for a temporary dwelling-place for guests “magor”.
