Over the course of my life, I’ve occasionally had to write the number 40 down in its full written form. These occasions have included: on cheques, in a formal letter to my bank manager, and on birthday cards when the recipent has indeed been 40 years old and writing the number on its own seemed too informal.
Each and every time I’ve had to do it, I’ve spelt it fourty.
Well, I looked it up last night, and found out that it it isn’t spelt that way at all: it’s forty.
I feel like such a fool.
