Take a more esoteric example - to capitalise just the first letter of a string. By definition, this is called 'proper case', and most other languages I know use .proper() to achieve this. Except Ruby, which decided to use .titleize() (and there is that 'ize' again just to confound me further).
If a language is going to be 'English-y', then sticking to actual English words for things such as uppercase, proper case etc. would be handy. Going outside of those constraints just increases the guessing game workload for the programmer.
