1. To compress the throat of; to choke; to strangle.

Throttle \Throt"tle\, v. i.

1. To have the throat obstructed so as to be in danger of suffocation; to choke; to suffocate.

2. To breathe hard, as when nearly suffocated.

"strangle to death," c.1400, probably from Middle English throte "throat" (see throat) + -le, perhaps a frequentive suffix (as in spark/sparkle), or a utensil suffix (as in handle), or simply to distinguish it from throat (v.), which in late 14c. was used to mean "cut the throat of, kill by cutting the throat." Related: Throttled; throttling.

1540s, "throat;" it appears to be an independent formation from throat, perhaps a diminutive form, not derived directly from the verb. The mechanical sense is first recorded 1872, short for throttle-valve (1824). Full-throttle (allowing maximum speed) is from 1848 in reference to steam engines.

Etymology 1 n. 1 A valve that regulates the supply of fuel-air mixture to an internal combustion engine and thus controls its speed; a similar valve that controls the air supply to an engine. 2 The lever or pedal that controls this valve. 3 The windpipe or trache

Throttle is any mechanism by which the power or speed of an engine is regulated

Throttle or throttling may also refer to:

• Strangling
• Throttle (film), a 2005 thriller
• "Throttle" (novella), a 2009 novella by Stephen King and his son Joe Hill
• Bandwidth throttling, used to control the bandwidth that a network application can use
• Rocket engine throttling
• Throttling process (computing), software speed control
• Throttling process (thermodynamics), an isenthalpic process in thermodynamics
• DVD-by-mail throttling, the process of penalizing the most active users in subscription-based DVD-by-mail businesses, by slowing shipments or sending less desirable movies
• CPU throttling, computer hardware speed control, also known as dynamic frequency scaling
• Throttle, one of the three main characters of Biker Mice from Mars
• "The Throttle", a nickname for the American athlete Dave Wottle

A throttle is the mechanism by which fluid flow is managed by constriction or obstruction.

An engine's power can be increased or decreased by the restriction of inlet gases (i.e., by the use of a throttle), but usually decreased. The term throttle has come to refer, informally and incorrectly, to any mechanism by which the power or speed of an engine is regulated. What is often termed a throttle (in an aviation context) is more correctly called a thrust lever, particularly for jet engine powered aircraft. For a steam engine, the steam valve that sets the engine speed/power is often known as a regulator.

Throttle (also known as No Way Up) is a 2005 American thriller film starring Grayson McCouch. Other cast members include Adrian Paul and Amy Locane. It was filmed entirely in Denver, Colorado.

Throttle is a novella written in co-authorship by Stephen King and his son Joe Hill. It was published in February 2009 by Gauntlet Press in a limited edition anthology honoring Richard Matheson titled He Is Legend, and in a mass-market audiobook titled Road Rage, also containing Matheson's short story "Duel", which served as inspiration for Throttle. A comic book adaptation by IDW Publishing was published in the spring of 2012.
