SKEDADDLE.
This word may be easily traced to a Greek origin. The verb σκεδαννυμι, of which the root is σκεδα, is used freely by Thucydides, Herodotus, and other Greek writers, in describing the dispersion of a routed army. From the root σκεδα the word skedaddle is formed by simply adding the euphonious termination dle and doubling the d, as required by the analogy of our language in such words. In many words of undoubted Greek extraction much greater changes are made.
The Swedes have a similar word, skuddadahl, and the Danes another, skyededehl, both of which have the same signification.
An old version of the Irish New Testament contains the passage, “For it is written, I will smite the shepherd, and the sheep of the flock shall be sgedad ol.” This compound Irish word sgedad ol (all scattered or utterly routed) was probably used by some Irishman at Bull Run, and, being regarded as felicitous, was at once adopted.
