So I bought the book. I bought it at Carry Farm (with typical restraint, they only had this one title for sale).
The author is a lifestyle journalist and suggests that 'coorie' is now a trend, a movement. Well, why not? It's a lovely word I have known since childhood. Perhaps 'snuggle' is the closest translation. You might say 'Coorie in' to a child needing a little comfort and invite them to sit beside you and put your arm around them. Or you might 'Coorie doon' (down) as I have been doing for a few days nursing a cold.
It has in it affection and safety and a sense that right here right now, all is well. Such a winderful and important feeling to have. So I am all for promoting The Art of Coorie.
Cultural appropriation? No! Sharing of cultural ideas to my way of thinking.
