Found on the Shelf While Looking for Something Else

This time it was John Pepper's Ulster-English Dictionary. I'd forgotten I had it. Pepper can be very funny and he's one of the few who can phoneticize the Ulster accent. And it's actually pretty informative as a dictionary, too.
Thus:

oxtercog, assist by holding under the arms: 'We hadda oxtercog the oul blether the whole way home.'

Find that in your Webster's Third International.
