Where does sidle come from?
The word is recorded from the late 16th century and is generally explained as a formation from “side” with a suffix used to indicate a small or limited movement. Its early history is tied to the idea of moving laterally rather than directly. The verb later developed the stronger sense of moving sideways in a furtive or furtively cautious manner, while the noun denotes the movement itself.
