Word Story
At its most literal, the word describes a surface that rises and dips in small, irregular swells, so that a hand dragged across it never travels in a straight line. The more common use in everyday speech is figurative: a period, a process or a relationship can be called bumpy when it advances through setbacks rather than in one clean motion. There is a gentle quality to the complaint — calling something bumpy usually suggests minor jolts rather than disaster, which is why it turns up so often in reviews of flights and first drafts of plans. Air travel is where most people meet it in the wild: a descent through rough weather is described this way, and pilots refer to turbulent stretches as bumpy air over the intercom. It also shows up in sports commentary and business writing, where a promising but uneven season or launch is rarely called anything else.
