The plural form of 'axis' is 'axes'. This word, derived from Greek, is interesting because it changes completely when moving to plural form. This is one of the instances in English where plurals can be tricky. Unlike regular nouns ending in 's' or 'es', 'axis' becomes 'axes', pronounced like "ax-eez". Always remember this when you're discussing more than one axis. It's simply one of the numerous quirks of the English language!
