overdrive
UK: ˌəʊvəˈdraɪv | US: ˌoʊvərˈdraɪv
n. 1. A gear mechanism in vehicles that allows higher speed with reduced engine power.
n. 2. A state of intense or excessive activity.
vt. 1. To push (a system or person) beyond normal limits.
The word "overdrive" combines "over" (Old English ofer, meaning "above" or "beyond") and "drive" (Old English drīfan, meaning "to propel or force forward"). Originally used in mechanical contexts (early 20th century) to describe a gear ratio for higher speed, it later metaphorically extended to describe excessive effort or hyperactivity. The morphemes retain their original spellings, reflecting the word's logical construction.
