Many words contain metaphors drawn from the older and simpler trades. We speak of a thing being "brand-new"--that is, as new as though just stamped with a "brand" or iron stamp. Another expression which has changed its meaning a little with time used to have exactly the same meaning. We now say a person looks "spick and span" when he or she is very neatly dressed. Formerly the expression was "spick and span new"--that is, as new as a spike (or spoon) just made or a chip newly cut. We may safely say that very few people who now use the expression "spick and span" have any idea of what it means literally. The metaphor is well hidden, but it is there. Another metaphor, connected with metals and coins, is contained in the word _sterling_. We speak of "sterling qualities" or a "sterling character" in praising people for being straightforward and truthful, and not boastful. But the expression originally applied only to metals and coins. Sterling gold or silver is gold or silver of a certain standard of purity and not mixed with too much of any base metal. Even the art of the baker has given us a word with a hidden metaphor. We speak of sending out another "batch" of men to the front; but _batch_ originally meant, and still means, the loaves of bread produced at one baking. It is now used generally to describe a number of things coming together or in a set. The butcher's shop has given us the word _shambles_, by which we now mean a place of slaughter. Thus we speak of a terrible battlefield as a "shambles." This metaphor is really due to a mistake. People came to think that a shambles was a singular noun meaning slaughter-house, or place where cattle were killed; but really the shambles were the benches on which the meat was spread for sale. We speak of a person being the "tool" of another, and this is a metaphor taken from the general idea of work. The "tool" is merely used by the other person for some purpose of his own, just as a workman uses his tools. The greatest poem, or book, or picture of a poet, writer, or painter is often described as a "masterpiece." This word now means a "splendid piece of work," but in the Middle Ages a "masterpiece" was a piece of work by which a person working at a trade showed himself sufficiently good to be allowed to be a "master." Before that he was a "journeyman," and worked for a master himself, and, earlier still, an apprentice merely learning his trade. We often now use the expression to try one's "'prentice hand" on a thing when we mean that we are going to do a thing for the first time. The commonest actions have naturally given us most metaphorical words, for these were the actions of which the word-makers were most easily reminded. We speak of our passions or emotions being "kindled," taking the metaphor from the common action of lighting a fire.
