Synonym discussion
Sense: noun/1
Teeter-totter and seesaw usually name the same playground ride: a long board that goes up and down with a child at each end. Seesaw is the broader and more widely used word, especially outside North America. Teeter-totter sounds more American and often appears in school, park, or family contexts. Teeter can also be used for the same ride in some American speech, but it is shorter, less common, and easier to confuse with the verb teeter, which means to wobble or nearly fall. If you want the safest general word, use seesaw. If you are talking about American playground equipment, teeter-totter sounds especially natural.
Common collocations
Etymology
Teeter-totter is an English doubled form built from teeter, an expressive word for shaky rocking. The repeated shape of the word suggests back-and-forth motion, which fits the way this playground board rises and falls from side to side.
