How do you write teacher in Welsh?

There are two ways to write "teacher" in Welsh, depending on the gender of the teacher:

* For a male teacher: athro (pronounced "ath-ro")

* For a female teacher: athrawes (pronounced "ath-raw-es")

So, if you are talking about a specific teacher, you would use the appropriate gendered form. If you are talking about teachers in general, you can use the masculine form athro as a general term.
