I know what the C stands for, while it does cascade, it’s not inheritance and it always lends itself to “why does this have this style? I didn’t want that!”.

It's absolutely inheritance.

  .animal {
    font-weight: bold;
  }
    .animal.bear {
      color: brown;
    }

  <div class="animal bear">...</div>
