uppermost

最上面的、最高的、最顶端的

The uppermost branches of the tree were covered in snow.

树木最上面的枝条都覆盖著积雪。

最重要的、首要的

Safety was the uppermost concern in everyone's mind that day.

那天安全是每个人心中最重要的考量。

在最上面、在最高处

Place the heaviest boxes at the bottom and the fragile ones uppermost.

把最重的箱子放在下面，易碎的放在最上面。

最先、首要地

Her children's future was uppermost in her thoughts.

她心里最先想到的就是孩子们的未来。
