regurgitation

Regurgitation is not quite the same as vomiting, though they are related. It means material flows back up from the stomach or esophagus, often with little effort. Unlike vomiting, which is usually forceful, regurgitation is often passive. Think of a baby spitting up after a meal or stomach acid coming back up in reflux. Beyond the body, it also has a common figurative meaning: a student might repeat facts for an exam without really understanding them, or a politician might repeat the same old talking points. Whether it involves food or ideas, the main sense is that something comes back up or is repeated in much the same form.

Regurgitation describes the process of bringing material back up into the mouth from the esophagus or stomach. In a medical sense, it is usually effortless, which helps distinguish it from vomiting, a more active and forceful process. It is a common symptom in conditions like acid reflux or GERD, where stomach contents flow back into the esophagus. However, it is not always a sign of trouble; in the animal world, it can be useful or necessary. Birds regurgitate food to feed their chicks, and ruminants like cows bring up cud to chew it again and support digestion.

The word also has a strong figurative use. To "regurgitate" information means to repeat it mechanically without really understanding it. If a critic says a movie is just a "regurgitation" of better films, they mean the director has added little that feels new, instead repeating ideas already taken in from other sources.

The word comes from Latin roots: re- meaning "again" and gurgitare meaning "to flood" or "to gush." Whether you are talking about body functions, animal behavior, or repeated ideas, regurgitation always suggests that something already taken in is coming back again rather than becoming something new.
