What does gaol mean?
Gaol is chiefly a British term for a prison or other place of lawful confinement. It is pronounced like jail, with an initial /dʒ/ sound, and is also occasionally used as a verb meaning to imprison someone. The word appears in legal reporting, historical accounts, and formal British English, while American English normally uses jail. Although gaol and jail overlap in meaning, the former preserves a traditional British spelling and a somewhat more institutional register. Gaol can refer to a prison as a whole or, historically, to a particular building or secure room within one. The expression "gaol bird" is a dated or informal term for a prisoner. Knowing gaol is especially useful for understanding older British writing, news archives, and cultural references, where replacing it automatically with prison may obscure the word's distinctive history and tone.
A prison or place where people are lawfully confined, especially one for people awaiting trial or serving a sentence.
"He was held in gaol for several weeks before being released without charge."
Chiefly British and formally used; in American English, jail is the usual term.
To confine or imprison someone, especially as an official punishment.
"The magistrate sentenced the defendant to be gaoled for three months."
Now uncommon and more typical of formal legal or historical language.
The plural is grammatically standard but uncommon, because gaol is often used collectively for a prison or penal institution.
"The county operated separate gaols for men and women."
Gaol sounds like jail—but it preserves an older word: its root meant "pen" before it meant "prison."

Where does gaol come from?
Gaol entered English from French, through Old French gaole, with a meaning related to a prison or place of enclosure. Its ultimate source is a Vulgar Latin form derived from Latin cavea, meaning a hollow space, pen, or enclosure. Words such as cage, cave, and cavern preserve the same broad Latin root, while gaol eventually became specialized to mean a prison.
