tang

The tang of lemon juice brightens many dishes: that sharp, lively taste is what we call a "tang." The word is often used for food and drink, but it can also describe a strong smell, like the tang of sea air or metal. In both cases, it suggests something sharp and easy to notice.

You might say a cheese has a pleasant tang, or that there was a tang of smoke in the room. Sometimes the word is also used more loosely for a clear hint of something in a mood, feeling, or remark, though that is less common. The idea is simple: it is that extra sharp note that stands out right away.

The word "tang" most often refers to a strong, sharp taste or smell. In food, it usually means an acidic, zesty, or pleasantly sharp flavor, like the tang of lemon juice, yogurt, or a well-aged cheese. For smells, it often suggests something crisp and striking, such as the tang of sea air, smoke, or metal. In both senses, the word points to a quality that is vivid and hard to miss.

You can use it for pleasant things and unpleasant things alike. A sauce can have a fresh tomato tang, while water can have a metallic tang. The common thread is not whether the experience is good or bad, but that it has a clear, sharp character. The word is sometimes extended to mean a noticeable hint of something less physical, such as a tang of sadness or irony, but that use is more figurative and less common than the taste and smell senses.

The history of the word helps explain its feel. It comes from an older idea of a sharp point or sting, which fits the way a sharp flavor or smell seems to "hit" the senses. So when people use "tang," they are usually talking about that lively edge in taste or smell, and sometimes, by extension, a strong hint of the same kind of sharpness in a feeling or tone.
