Thank you for answering my earlier post; however I am still uncertain of how you would say: "she is a good professor".
Elle est bon professeur??? Elle est bonne professeur??
Also, I know that one would not use the personal form when speaking to a teacher but if teacher and adult pupil were friends (both female), how would you say:
From your good student???
I know it is:
"ton amie" and "ton étudiante" because amie and étudiante start with a vowel, but if one would add "bon" would it then be:
"ta bonne amie" and "ta bonne étudiante:???
Thank you
Or is it: elle est un bon professeur
or: elle est une bonne professeur
To say "she is a good professor" in French, you would say "elle est une bonne professeure." Note that "professeure" is the feminine form of "professeur" and includes the additional "e" at the end.
For the second question, if a teacher and adult student were friends and both female, and you wanted to say "from your good student," you would say "de ta bonne étudiante." The possessive form "ta" is used because the person being referred to is feminine, and "bonne" agrees in gender with "étudiante." So your understanding of "ta bonne amie" and "ta bonne étudiante" is correct in this context.
