I'm wondering how do you pronounce letters when used in place of ordinal numbers.
- The xth root of five.
- Two to the yth power.
- The ith odd number.
- The jth item on the queue.
I know how to pronounce nth, i.e. /ɛnθ/, but I don't think that I can do the same with x, y or other letters (I find it really hard to pronounce /ɛksθ/). Should I spell x-t-h?
