Again, you will perceive that many words once had more literal or more definitely concrete meanings than they have now. To corrode is to gnaw along with others, to differ is to carry apart, to refuse is to pour back. Polite is polished, absurd is very deaf, egregious is taken from the common herd, capricious is leaping about like a goat, cross (disagreeable) is shaped like a cross, wrong is wrung (or twisted). Crisscross is Christ’s cross, attention is stretching toward, expression is pressed out, dexterity is right-handedness, circumstances are things standing around, an innuendo is nodding, a parlor is a room to talk in, a nostril is that which pierces the nose (thrill means pierce), vinegar is sharp wine, a stirrup is a rope to mount by, a pastor is a shepherd, a marshal is a caretaker of horses, a constable is a stable attendant, a companion is a sharer of one’s bread.
On the other hand, you will find that many words were once more general in import than they have since become. Fond originally meant foolish, then foolishly devoted, then (becoming more general again) devoted. Nostrum meant our own, then a medicine not known by other physicians, then a quack remedy. Shamefast meant confirmed in modesty (shame); then through a confusion of fast with faced, a betrayal through the countenance of self-consciousness or guilt. Counterfeit meant a copy or a picture, then an unlawful duplication, especially of a coin. Lust meant pleasure of any sort, then inordinate sexual pleasure or desire. Virtue (to trace only a few of its varied activities) meant manliness, then the quality or attribute peculiar to true manhood (with the Romans this was valor), then any admirable quality, then female chastity. Pen meant a feather, then a quill to write with, then an instrument for writing used in the same way as a quill. A groom meant a man, then a stableman (in bridegroom, however, it preserves the old signification). Heathen (heath-dweller), pagan (peasant), and demon (a divinity) had in themselves no iniquitous savor until early Christians formed their opinion of the people inaccessible to them and the spirits incompatible
