According to The Guardian, an actress has...
...previously expressed her eagerness to flex her vocal chords on a guest spot on Glee, and for a spell was attached to a Judy Garland biopic.
Aha! I thought. There's a topic for a post. Because, you see, there are cords in your throat that vibrate to produce sound. Several people's vocal cords vibrating at the same time will produce a chord.
So I go to the OED. I look up cord. I get down to section 2.b and there it is.
Now applied generally to a nerve trunk, and spec. to certain structures, esp. the spermatic cord, spinal cord, and umbilical cord, the vocal cords; see these words.
Ok. I'll see those words. I turn to the entry for vocal and to my shock and flabbergasterment, I see this in section 6.a:
Operative or concerned in the production of voice. Freq. in vocal chord, vocal fold, vocal organs, vocal tract, etc.
So I can't really criticise The Guardian at all. Or if I did, I'd have to sneer at the OED too, which is blasphemous. I would have no lexicographical backing or supply chain. I would just be alone, muttering maledictions, straining my vocal kords, and shouting myself horse.
The Inky Fool was feeling a little horse that day.
