Canikin is an old-fashioned term used to refer to a small metal pot or jug that was used for heating or serving drinks. The word canikin has fallen out of use in modern times, and we have a few synonyms that can be used instead. These include a tankard, a mug, a cup, a pitcher, a flask, a cauldron, a kettle, or a saucepan. All of these terms describe a container that can be used for boiling or serving hot drinks, soup, or snacks. While the canikin may have gone out of fashion, its function has remained the same and there are several other words that can be used to replace it.
