Thanks James, I usually have a doubt with “whom”, In this case I was thinking about to write “who”, and the forum allows me to ask before and that is great for me. English grammar is not easy. Leonor
Do not feel bad. Believe me: most native speakers do not really understand the use of those two words.
I urge you to learn the use of those words, for this knowledge will help you in your career if you plan to do a lot of writing. I have no doubt that people respect speakers (and writers) who show that they have command of those two words.
If you study the matter hard, you CAN learn them. Sometimes, however, even the best educated native speakers have to think about the matter before choosing the correct pronoun.
Whenever you have a question about which pronoun to use in a particular sentence, just post it in this forum. You will receive many answers.
