Are you doing your utmost or your upmost? Confusion between these two words probably comes from people hearing utmost (which is the correct choice in this case, btw) as upmost (which is otherwise a pretty uncommon word). This may be because up seems like it should fit situations involving the highest effort. And, in fact, there are some cases where the two words can be used in the same situation, such as when describing words like concern or importance. Even if you’ve done your utmost to use upmost correctly, it’s still possible to get the two utterly mixed up. Let us help clear things up. ⚡️ Quick summary Utmost is commonly used as an adjective meaning maximum, greatest, or to the highest degree—or as a noun meaning the best of one’s abilities or the maximum limit.

Utmost is typically used in contexts that involve things being at the utter limit or the outer limit. When you do your utmost, you go all out. The utmost point is the one that’s farthest out. Upmost, on the other hand, is usually about things that are the highest up—often in terms of physical height or priority (think of the top item on a list). If you’re describing something as being the greatest or the maximum among all options, either word might serve. But utmost is usually the right choice. Even though utmost can mean the same thing as highest, you wouldn’t use it to describe the top floor of a building. And, to be honest, you probably wouldn’t use upmost either (even though that’s what it properly means). In many cases, it may be best to replace upmost with uppermost, or topmost, or whatever word is clearest for a particular situation. In general, keep in mind that utmost is much more commonly used than upmost.
