If you have ever expressed yourself on an express train, you may have wondered about the origin of the expression and why it should expressly mean that. You may then have settled down with an espresso and forgotten all about it.
Once upon a terribly long time ago there was a Latin word
exprimere, which meant to press out, and the past participle of which was
expressus. When you press your seal* into soft wax you produce an image, and, so far as anybody can tell, that's why the Latin word took on the meaning of describing or representing something.
Cows
expressed milk, sores
expressed pus and human beings were
expressed by God. Very quickly people got the idea of
expressing thoughts as words, as though the mouth were the udder of the mind. Thus Chaucer's:
Thy virtue and thy great humility
There may no tongue express
Also from this came the idea of something that was specifically, or
expressly, designed for one purpose
and for no other. If God expressed man, he did it rather well, or at least that's what Hamlet thought:
What a piece of work is a man! how noble in reason! how infinite in faculty! in form and moving how express and admirable! in action how like an angel! in apprehension how like a god!
We still use this meaning when we say expressly. Thus today's
Guardian:
In a work expressly intended for students to perform, Pountney has created a dramatic structure that interlocks three stories of 20th-century student political action...
So how do you send a letter? Do you entrust your epistle to the general mail, or do you employ somebody expressly to deliver it? Do you find a chap, give him one letter and express instructions? If so, then you have sent the letter
express.
The same sort of thing happened to trains. Some trains dawdle. They may say on the front that they are going to Euston, but once aboard you discover that they are in no great hurry to get there and that you will probably be pausing at Moreton-St-Davids for an hour or so while they load up the baggage car with sheep. What you need is a train that is meant
expressly and exclusively for Euston, a train that does not stop anywhere else.
These days express trains aren't very express and will probably terminate at Preston on a whim, but that's not how it once was, dear reader.
And so a word that meant
press out came to mean
describe and
intentional and
specific and
fast and
non-stop.
And
espressos? Though an espresso should be drunk quickly and is probably expressive of something or other, the dwarf coffee owes its name to the original Latin. You see, the steam is
pressed out through the coffee grains and into the bonsai cup.
Like a cow expressing milk
*By which I mean a coat of arms, not a marine mammal. I made that mistake once and the zookeeper got cross.
