One of the areas where lexical variation can be found is in the discourse of childhood pastimes. In the worksheets of the Linguistic Atlas of the Western States, one of the prompts elicits names for a board on a fulcrum, typically on a playground, that moves up and down when one or more children are seated on both ends of it. Probably, the two most recognizable terms for this artifact in the United State are teeter-totter and seesaw, with one or the other prevailing in various regions and, perhaps, different time periods. The question was put forth to informants of the Linguistic Atlas of the Middle Rockies with the following results:

As illustrated, teeter-totter is clearly the preferred variant in the collection. While many informants did admit having heard of seesaw, several did not know the variant at all, or reported being only familiar with it through old literature or nursery rhymes and the like.
