Fix typos

[entorb]

Thanks!

I just followed your example and checked for more occurrences via the following regex / a [aeio]/

Could a native speaker please check if any of the other 14 hits needs fixing too? For example using grep: grep ' a [aeio]' chapters/*.tex

I missed one in chapter 58, I think all the ones with that grep ' a u' chapters/*.tex finds are correct though

edit: I didn't see you used [aeio], I used [aeiou] :sweat_smile:

Many thanks, both of you!
