I see that I am not the first to complain about this. Ordered the stirling single on July 24. received acknowledgement. shipment never confirmed. two emails not answered, although my payment was speedily accepted. unprofessional. please help!
Yes it‘s joking Neo-Latin, not archaic or classical, quite a well-known scurrilous ludicrosity. illigitimis is dative plural, as is normal for the agent with a gerund. It continues the proto-indo-european thematic instrumental in *-o:ys, itself quite a problematic ending.
I must say I like this forum very much and enjoy the members‘ humor!
