Overbrake

Part of speech: noun, verb

Definitions

1. To apply excessive braking to a vehicle, leading to compromised control or an increased stopping distance

3. To engage the braking system too aggressively, which may result in tire lockup or loss of traction on the road

Etymology: "Overbrake" is about as plain as English compounds get: it joins the prefix "over-", meaning excessively or beyond the proper amount, to "brake", the device or action of slowing a vehicle. Put together, the sense is simply to brake too hard, so that the vehicle stops more abruptly than intended. The prefix is the productive part of the word. "Over-" attaches freely to verbs and nouns in English to mark excess, which is why speakers can coin a term like this on the spot without it being a set expression. The word works as both a noun and a verb, following the usual pattern for words of this kind. As a verb it describes the act of applying the brakes too forcefully, and as a noun it names the result or the instance of doing so. Because the parts are transparent, its meaning can be worked out from its make-up, and it has little of the drift in sense that older, more deeply rooted words often show.
