How would you say:

she is a good professor
and
I (feminine) am your good student
thank you

Is it: elle est un bon professeur, or

elle est une bonne professeur
and:
Je suis ta bonne étudidiante

And: for my good professor (female)

pour ma bon professeur?????

It is either le professeur OR la femme professeur. I would not use "ta" to a teacher but "votre."

oops = forgot to sign it!

Sra (aka Mme)

But how would you use the sentence:

She is a good teacher?
and
For my good teacher (if the teacher is female.)????

Also, I realize that one does not use the personal form with a teacher; however if there are two friends and one is the teacher and the other the student (both females) then how would you say:

from your good pupil?
I know that it is " ton ètudiante" but if I interject the "bon" would it then be: ta bonne ètudiante ???

To say "she is a good professor" in Spanish, you would say "ella es una buena profesora." To say "I (feminine) am your good student," you would say "yo soy tu buena estudiante." Here's the breakdown of the translations:

1. "She is a good professor":
- "She" is translated as "ella" in Spanish.
- "Is" is translated as "es."
- "A good professor" is translated as "una buena profesora."

2. "I (feminine) am your good student":
- "I" (feminine) is translated as "yo" in Spanish.
- "Am" is translated as "soy."
- "Your" is translated as "tu."
- "Good student" is translated as "buena estudiante."

Remember, in Spanish, adjectives agree in gender and number with the noun they modify. In these sentences, both "profesora" (professor) and "estudiante" (student) are feminine nouns, so the adjectives "buena" (good) and "buena" (good) also take the feminine form.
