plummy

"Plummy" started as a descriptive word for something that seems like a plum in some way: rich, ripe, juicy, dark, soft, or full in flavor or sound. In that older, literal sense, it can describe food, drink, color, or even a rich texture. A sauce, wine, or voice may all be called "plummy" if they feel deep and full.

Today, the word is especially common in British English when talking about speech. A "plummy" voice or accent sounds rounded, rich, and noticeably upper-class. It often suggests a carefully polished or slightly affected style of speaking, the kind of accent people may connect with private schools, old wealth, or formal public speech.

There is also another use based on the noun "plum," where a "plum" job or role is a very desirable one. From that sense, "plummy" can describe something especially choice, rewarding, or attractive, such as a good appointment or a sought-after acting part. That meaning exists, but it is not as central as the use about voice and accent.

So the word usually points in one of two directions: either something rich and full, like ripe fruit, or a rich, posh-sounding way of speaking. In some contexts, it can also hint at a particularly desirable role or opportunity.
