Usage

What is a basic definition of release? Release means to free from imprisonment or confinement, to free from anything that is acting as a constraint, or to allow something to be out in the open. The word release has many other senses as a verb and a noun. When a person is released, they are freed from their captivity or anything else that was hindering their freedom. This sense of release is an antonym of words like imprison, detain, or confine.

• Real-life examples: A person is released from prison once they complete their sentence. For the most part, a person is released from debt if they declare bankruptcy. Parents often force children to release wild animals back to wherever they came from.
• Used in a sentence: Whenever I go fishing, I always release the fish back into the water after catching them. 

Release is also used in this same sense as a noun.

• Used in a sentence: The king paid for the release of his son from the enemy. 

Release is also used figuratively to mean to free anything from any kind of restraint.

• Used in a sentence: I released the rope and let it fall down into the hole.  

Release can also mean to allow something to be freely distributed or sold to the public.

• Real-life examples: Authors release new books. Musicians release new albums. The government sometimes releases information to the press. Researchers release the results of tests or studies to the public.
• Used in a sentence: Stephen King just released a new book that I really want to read.

Synonym Usage

Release, free, dismiss, discharge, liberate, emancipate may all mean to set at liberty, let loose, or let go. Release and free, when applied to persons, suggest a helpful action. Both may be used (not always interchangeably) of delivering a person from confinement or obligation: to free or release prisoners. Free (less often, release ) is also used for delivering a person from pain, sorrow, etc.: to free from fear. Dismiss, meaning to send away, usually has the meaning of forcing to go unwillingly ( to dismiss a servant ), but may refer to giving permission to go: The teacher dismissed the class early. Discharge, meaning originally to relieve of a burden ( to discharge a gun ), has come to refer to that which is sent away, and is often a close synonym to dismiss; it is used in the meaning permit to go in connection with courts and the armed forces: The court discharged a man accused of robbery. Liberate and emancipate, more formal synonyms for release and free, also suggest action intended to be helpful. Liberate suggests particularly the release from unjust punishment, oppression, and the like, and often means to set free through forcible action or military campaign: They liberated the prisoners, the occupied territories, etc. Emancipate also suggests a release of some size and consequence, but one that is less overt, a more formal or legal freedom; and it sometimes connotes an inner liberation: Lincoln emancipated enslaved African Americans. John emancipated himself.

Etymology

Origin of release

First recorded in 1300–50; Middle English verb reles(s)en, relecen, from Old French relesser, relaissier, releiss(i)er, from Latin relaxāre “to loosen, stretch out”; Middle English noun reles(s)e, releise, from Old French reles, relais, releis, back formation from relesser, relaisser, releiss(i)er; see origin at lax, relax

Explanation

To release something or someone is to set it free, like a caged animal or a prisoner. “I shall be released” is a famous refrain from a 1967 Bob Dylan song that has come to symbolize political freedom around the world. Release, which is a noun and a verb, has many different meanings. As a noun, it can mean a liberation, an unfastening, or the condition of being made available, like a movie or a CD. “When is the new Spiderman movie being released?” you might ask your best friend. As a verb, it can mean to relieve of suffering or obligation, like a debt. But it can also mean to lay off from a job, or surrender. “Release me from having to watch this terrible movie!” you could end up saying about the 16th Spiderman sequel. And who would blame you?
