Scourge

To whip, beat, or thrash severely. Also as a noun, the instrument of punishment.

Once again, I would have told you that I knew what scourge means. And I would have been gen­er­al­ly sort of right. I would have used it in cer­tain con­texts as a syn­onym for threat or to mean a dam­ag­ing influence. 

But when I came across the sec­ond Por­cian law, which accord­ing to [wikipedia](http://en.wikipedia.org/wiki/List_of_Roman_laws), «pro­hibits scourg­ing of cit­i­zens with­out appeal», it became painful­ly clear that I had no idea of its spe­cif­ic mean­ing. Now it’s 2:30 in the morn­ing and I’ve spent the last few hours research­ing def­i­n­i­tions from read­ing two or three para­graphs ear­li­er this after­noon, includ­ing a word I had to look up in the mid­dle of look­ing up oth­er words! Is there any won­der why I’m nine books behind on my 52-in-52?
