A John Cowan comment reminded me I wanted to post about the word obnoxious, which must surely be one of the most difficult words to deal with in reading old documents, since its meaning has changed so confusingly. I discovered this while reading Peter Brown’s Through the Eye of a Needle; in the course of describing how Pope Gelasius helped keep the slaves working for their masters (so the grain would keep flowing from southern Italy to Rome), he writes:
Gelasius was told that many who became priests and deacons had been slaves. Many more had been obnoxii—farmers permanently tied to the estate on which they were registered as taxpayers. Clerical status freed them from these bonds.
Naturally, I wondered about obnoxii, so I looked up obnoxious in the OED (entry updated March 2004), and this is what I found:
Etymology: < classical Latin obnoxiōsus subject, subordinate < obnoxius exposed to harm, liable, answerable, submissive, subject to punishment ( < ob– ob- prefix + noxa hurt, injury (see noxious adj.) + –ius, suffix forming adjectives) + –ōsus -ous suffix.
In senses 4 and 5 probably immediately after noxious adj.
a. Liable, subject, exposed, or open to a thing (esp. something actually or possibly harmful). (The usual sense before the 19th cent.) Now rare.

The transitions between the senses are perfectly clear (liable to > subject to > open to punishment or censure; guilty, blameworthy > offensive, objectionable, odious), and yet I look at some of those early quotes and think “If I ran across that in my reading I would be completely at a loss.” When you’re used to the modern sense, it would take a lot of immersion in earlier usage to properly interpret “obnoxious to its foes,” “some other less obnoxious quarter,” “wholly obnoxious to them,” “obnoxious to God alone,” or “obnoxious to the Association for preserving the Game.”
