And in many others the authentic American is no less plain, for example, in to kick the bucket, to put a bug in his ear, to see the elephant, to crack up, to do up brown, to bark up the wrong tree, to jump on with both feet, to go the whole hog, to make a kick, to buck the tiger, to let it slide and to come out at the little end of the horn. To play possum belongs to this list. To it Thornton adds to knock into a cocked hat, despite its English sound, and to have an ax to grind.

Among the coinages of the first half of the century that are in good use today are non-committal, highfalutin, well-posted, down-town, two-fer, played-out, flat-footed, whole-souled and true-blue. The first appears in a Senate debate of 1841; highfalutin in a political speech of the same decade. Both are useful words; it is impossible, not employing them, to convey the ideas behind them without circumlocution. The use of slim in the sense of meagre, as in slim chance, slim attendance and slim support, goes back still further. The English use small in place of it.

But the essentially American character of most of them is obvious, despite the fact that a number have gone over into English. The English, in naming their drinks, commonly display a far more limited imagination. Seeking a name, for example, for a mixture of whiskey and soda-water, the best they could achieve was whiskey-and-soda. The Americans, introduced to the same drink, at once gave it the far more original name of high-ball. So with ginger-ale and ginger-pop.
