Usage
What’s the difference between overwhelm and underwhelm? The over- in overwhelm means “too much” and the under- in underwhelm essentially means “too little,” and the two words can be direct opposites, but they’re usually used in different contexts. Overwhelm most commonly means to cause to be overcome with emotion as a result of an amount of something (work, stress, etc.) that’s just too much to handle. (It can also mean to overpower or physically cover beneath a mass of something). Underwhelm means to fail to impress, especially when that is the expectation. Both words are often used in adjective forms: overwhelmed (overcome to the point of not being able to manage), overwhelming (describing something that leads to feeling overwhelmed), underwhelmed (unimpressed or disappointed), and underwhelming (unimpressive or disappointing). Being overwhelmed isn’t always about stress or other negative emotions. You could be overwhelmed by a friend’s generosity or the birth of a child. Still, it’s usually about feeling a lot. In this way, underwhelm can be the opposite of overwhelm in some situations. For example, the same concert may overwhelm one person (perhaps it’s the first concert they’ve ever attended) but underwhelm someone else (maybe because it doesn’t meet their high expectations). And, yes, whelm is a word. It can mean the same thing as overwhelm, but it’s very rarely used. Here’s an example of overwhelm and underwhelm used correctly in the same sentence. Example: I never want to underwhelm the fans, and sometimes that pressure can overwhelm me, but it all goes away when I walk on stage. Want to learn more?

Etymology
Origin of overwhelm
A Middle English word dating back to 1300–50; see origin at over-, whelm
Explanation
Overwhelm means “give a person too much of something.” If your friend agrees to feed your pet fish while you’re on vacation, don’t overwhelm her with requests by also asking her to do your laundry and wash the dishes. While it’s easy to be overwhelmed by chores or complaints, it’s also possible to be overwhelmed by good things — if they occur in large quantities. You might enjoy a stack of pancakes for breakfast, but you'd probably find a truckload of pancakes overwhelming. Sometimes people feel overwhelmed by emotion, and this can be a positive or negative experience, depending on the emotion. For example, you might feel overwhelmed by gratitude if your friend takes excellent care of your fish, but overwhelmed with grief if the fish is accidentally flushed in your absence.
