What does phial mean?
A phial is a small bottle, usually made of glass, for containing medicine or another liquid. Its narrow neck and compact size make it particularly associated with traditional medical and pharmaceutical packaging: a doctor or apothecary might dispense a remedy in a phial, and an empty medicine phial might once have been reused for pills or liquids. The word remains common in British English, especially when the container's small size or medicinal purpose is relevant, but it is uncommon in general American usage, where vial is normally preferred. Phial can also appear in descriptions of perfumes, essential oils, specimens, and decorative objects presented as tiny bottles. The distinction from vial is chiefly one of emphasis and regional convention rather than a sharp semantic boundary. Both words can refer to much the same object, but phial often retains a slightly traditional, formal, or medicinal tone.

Where does phial come from?
Phial entered English through Middle French phial, which derived from Medieval Latin phiale, a term for a small vessel. Medieval Latin phiale was borrowed from Greek phialē, meaning a small bowl or vessel. The English word later became especially associated with small glass containers used for medicines, while the closely related form vial developed with broader uses.
