"Ask Courtney to teach him/her/them."
Here's a breakdown:
* Pregunte: Ask (formal, you would use this with someone you don't know well or are older than you)
* a Courtney: to Courtney
* que le ensene: that she/he/they teach him/her/them
It's important to note that the sentence doesn't specify who is being asked to teach, or who is being taught. You need more context to fully understand the meaning.
For example:
* "Pregunte a Courtney que le enseñe a tocar la guitarra." (Ask Courtney to teach him/her how to play the guitar.)
* "Pregunte a Courtney que le enseñe a hablar español." (Ask Courtney to teach him/her how to speak Spanish.)
