==Etymology==
Yan tan tethera, also called Sheep counting, is a sheep-counting rhyme/system traditionally used by shepherds in Northern England and earlier in some other parts of England and the British Isles. In order to keep accurate records (e.g. of birth and death) and to alert instances of straying, shepherds must perform frequent head-counts of their flocks. Dating back at least to the medieval period, and continuing to the present in some areas like Slaidburn, farms were granted fell rights, allowing them access to common grazing land. To prevent overgrazing, it was vitally necessary for each farm to keep accurate, updated head-counts.
Counting sheep is a mental exercise used in some cultures as a means of lulling oneself to sleep.
