‘Deadlock yarred through his bare teeth.’
‘Between his teeth the hound yarred…’
A word now apparently limited to dialect, but feel free to revive it more generally. If anyone snarls or growls at you, you can tell them to ‘Stop yarring’.
Deadlock is a lead dog in a pack of otterhounds and Tarka’s nemesis.
See also ‘belve’.
