What is the SE.Raspberry Pi accepted plural form of Pi. I have seen various offerings, some plausible, some grammatically correct but just look wrong, some which are just downright wrong... Some examples include:
This is be no means an exhaustive list, and there are probably some other variants. Taking each in turn:
- Pi's - this is grammatically a possessive;
- Pis - whilst grammatically correct, the spelling is somewhat unfortunate;
- Pi - treating the noun as a countable noun, with an irregular plural, where the plural is the same as the singular, like sheep;
- Pies - Whilst amusing, it is obviously not correct (although I wish it was).
I personally like the Pi option. It sounds more technical, and slightly old Germanic...
It first came to my notice whilst editing the ppumkin's answer to the question, Powering Pi with a 5V regulated power supply, but I also see other people are confused, see Maehler's answer to Seems a bit premature?
Anyone how any thoughts on the matter..? Whilst it is not the end of the Earth, a little consistency would be nice.
