* Dash comes from the Old English word "dassian", meaning "to strike, to rush". This word has roots in Proto-Germanic and ultimately connects to the Indo-European word "dēks", meaning "to prick, to pierce".
Let's look at the other options:
* Accelerate comes from Latin "accelerare", meaning "to hasten".
* Careen comes from French "carène", meaning "keel" (of a ship).
