A 67 year old lady at my job keeps calling the binder we share a tablet and every time she asks for it, I’m like, “what tablet?”. Yesterday I told her it’s a binder and she said it was called a tablet before my time. But all my grandparents are around the same age and they all call them binders. Was it a regional thing maybe? We’re in the US by the way.
I’ve heard it used to refer to Notebooks but only by much older people (and I’m already middle-aged myself). I’ve never heard a binder called that. But, the linked article does mention spiral-bound notebooks, so I wonder if that’s why she conflated it in her mind.
