A phial is a small glass container with a narrow neck, often used to hold liquids such as medicine or perfume. It is a formal or literary word and is not commonly used in everyday speech. You might encounter the word phial in scientific or medical contexts, or in literature. For example, a character in a story might open a phial of poison or a doctor might give you a phial of medication. If you are an English learner, it's good to know the word phial but you may not encounter it often in casual conversation.
