Upmost vs. utmost

When you need an adjective meaning (1) of the highest or greatest degree or (2) most extreme, the word is utmost. When you need an adjective meaning situated at the top, highest, or most upward position, the word you’re looking for is upmost. The latter is an old, almost archaic word that now mostly appears where writers obviously mean utmost.

Examples

Utmost

Clearly, the Panthers are doing their utmost to entice people to visit the rink. [Regina Leader-Post]

You can feel that the developers thoroughly enjoyed their work and each step was made with the utmost care. [Battle Creek Enquirer]

Upmost

After reversing the door, the operator shall return the door to, and stop at, the full upmost position. [Code of Federal Regulations, LSA]

  1. Thank goodness. Someone actually knows (and cares) about the difference. It drives me insane when upmost is used incorrectly.

  2. In the definition, “utmost” is described as an adjective, and in the first example that follows it is used as a noun: “doing their utmost” :/

    • “Utmost” is a superlative noun (the only way to define it is to use other superlatives; therefore, it’s a superlative).

      In English, at least colloquially, you can use a superlative without a noun, as if the noun is implied. “Do your best (work)!” “I am the fullest (one here).” “I drank the tastiest (one).” “The tallest (tree) is west.”

      • Surely, you mean a superlative adjective. Historically at least, and in some senses still, it’s the superlative of “out”; the comparative is utter. Out, utter, utmost.

        • Wow, yeah, my mistake. I can’t believe I typed that, haha. I didn’t realize “out” was an adjective in that sense. Must be out-dated.
