What I like about Scribal Terror blog is how Gail Hapke throws in a neat vocab lesson every now and then. Take this post on "feague", which means:
“to put ginger up a horse’s fundament, or a live eel, to make him lively and carry his tail well; it is said, a forfeit is incurred by any horse-dealer’s servant, who shall shew a horse without first feaguing him. Feague is used, figuratively, for encouraging or spiriting one up”.
(What's a fundament? The Free Dictionary to the rescue)
(Illustration: AWhitehorse, who obviouly doesn't approve of the whole ginger thingy)
