A word post could be a mile marker with something other than numbers on it.

Or a kiosk. Wouldn't that be a word post of sorts?

Or graffiti? That's a word post.

And isn't it interesting that ord is found both in word and sword? But not so interesting that it's found in ordinary.

An unoriginal writer could be described, however, as being wordinary; and a precictable, unthreatening foe in the days of duals coule have been described as being swordinary.

Then there's cord and cordinary and ford and fordinary and, oh, lord and lordinary...
