When i attended school in the sixties and seventies the term we used was a WHACKING both for canings and slipperings of which i received plenty
We also used to refer to ‘having been whacked’ or going to be whacked, when discussing amongst ourselves. I used to use this when speaking to my parents as well, telling them I haad been whacked at school.
When speaking to a teacher though, for some reason, I think I would have always used the term cane, caning or caned as appropriate to the situation. Strange that, never thought about that before.
