What does bail mean?
Bail is primarily a legal term referring to the system by which a person accused of a crime may be released from custody while awaiting trial, usually on condition that they or others pledge money or property to guarantee their appearance in court. The sum pledged is itself called bail, and phrases like 'post bail' and 'jump bail' are firmly established in both British and American English. Beyond the courtroom, the verb 'to bail' has acquired broader uses: to rescue someone from trouble, to withdraw from a commitment ('she bailed at the last minute'), or — in its oldest practical sense — to scoop water from a leaking boat. The word derives from the Old French verb baillier, meaning to deliver or entrust, making it a cousin of 'bailiff' and 'bailey'. Versatile and centuries old, bail sits at the intersection of law, finance, and ordinary speech.
Security, typically a sum of money, deposited to ensure that an accused person released from custody will appear for trial; also the release itself.
"Her lawyer argued successfully for a reduction in bail."
In many jurisdictions cash bail has been supplemented or replaced by bail bonds and non-financial conditions.
To secure the release of someone by providing bail; more broadly, to rescue from difficulty or to withdraw from a situation; also, to remove water from a boat.
"His uncle agreed to bail him out after the arrest."
The plural applies mainly to multiple pledges of security or, in cricket, to the small wooden pieces resting atop the stumps, which are also called bails.
"Both defendants posted their respective bails before Friday's hearing."
The word 'bail' once simply meant handing something over — the same root that gave us 'bailiff', the court officer who literally takes custody of you.

Etymology of bail
Bail comes from the Old French verb baillier, meaning to hand over, deliver, or entrust something to another's keeping, which itself descends from Latin roots associated with carrying or conveying. From the same source come bailiff (a custodian or officer), bailey (the outer ward of a castle), and the related term bale, a bundle handed over in trade. In medieval England, the practice of delivering an accused person into the custody of a surety rather than keeping them imprisoned gave rise to the modern legal institution of bail, attested in English legal records from the Middle Ages onward.
