If any lightfoot Clod Dewvale was to hold me up, dicksturping me and marauding me of my rights to my onus, yan, tyan, tethera, methera, pimp, I’d let him have my best pair of galloper’s heels in the creamsourer.
—James Joyce, Finnegans Wake
Though I grew up in the countryside, I’m not of direct farming stock, which may be why I learned of ‘yan tan tethera’ only quite recently. It’s an old counting system used traditionally by shepherds in parts of the UK, and also in knitting and fishing and so on, or by children for their own amusement.
