Other forms: overwhelming, overwhelmed, overwhelms
To overwhelm someone is to give them more than they can hold, so they stop coping altogether. A thousand emails after a week away. Grief that lands all at once.
You will meet it in the passive far more than the active: overwhelmed by, overwhelmed with — overwhelmed with work, overwhelmed by the response. Good things overwhelm too, so people are overwhelmed by kindness and by the size of the crowd that turned up. The physical sense is alive as well: floodwater overwhelmed the sea wall, and a small force was overwhelmed by a larger one. Overwhelming is the form doing most of the work in real sentences — overwhelming evidence, an overwhelming smell, an overwhelming majority. The prepositions are by and with, never from.
