Oppositelowest, bottom, bottommost
Note
A Middle English compound of upper and the superlative suffix -most, so the top position is built into the word. Strictly, that means it does not grade: nothing is more uppermost than the uppermost. Writers still reach for intensifiers, as in "more uppermost in my mind" and "the goals most uppermost," but the bare word is cleaner, and those phrases lean toward the "most important" meaning.
- 2Highest in rank or importance.
The safety of the passengers remained uppermost throughout the rescue.
Profit was uppermost in the negotiations, overshadowing every other issue.
Similarparamount, foremost, predominant, dominant, primary
Note
Importance usually sits after the noun or verb: a concern is uppermost, or it is uppermost in someone's mind, a phrase for whatever dominates a person's thinking at the moment. The word also stands before a noun, as in "the uppermost problem," where it means simply the chief or most pressing one. Either way it names a single winner among competing concerns.
- 3In the highest position; on top of everything else.
He arranged the documents with the signed contract uppermost.
When the crates were stacked, the lightest always rode uppermost.
Less common meaning
- 4Superlative of upper.
The uppermost windows of the tower caught the morning light.
Snow lingered on the uppermost slopes well into spring.
Note
As a plain grammatical superlative this reading is rare, because most uses fit the "topmost" adjective better. Taken strictly, it grades upper itself, which ranges from simply "at a higher level" to "on higher ground, further inland, or more northerly." So the uppermost slopes can mean the highest ones, and the uppermost stretch of a region can mean the part furthest upland.
