A “lob” – obsolete word – is a spider from Old English loppe.  But it’s also (separate word, spelled the same) a dialectical word for country bumpkin or a lout (a Scandinavian-rooted word).

Oh, yes.  This is why I did this.  One syllable.  Two obsolete words.  Classic bullying technique – what’s wrong with me calling you a spider?  It’s just a word for spider!  But we both know it means lout – and in Norse it means short and fat and clumsy and bumpkin.  Bilbo needed to pull out the big guns, word-wise, to distract the spiders from his friends, and he did it in three letters.  The master craftsman at play.
