As a linguist, I feel it is my duty at this point to indicate some other words that are said incorrectly all the time on this forum.
The correct plural of 'vortex' is is 'vortices'. Similarly, the numbers on cards are 'indices'. You could argue that those rules are old, so, 'vortexes' and 'indexes' is okay I suppose. But the plural is never vortex's or index's.
The correct plural of 'forum' is 'fora'. Again, you could argue that 'forums' is also correct, but unless you also say 'datums' instead of 'data' and 'agendums' instead of 'agenda' then you are being inconsistent.
Nevertheless, the Monarch version of these AIP bottle is my favourite so far. I never really was a fan of the Monarch cards themselves, and this way they are trapped from my reach forever!
