In this audio recorded in Portuguese language, I am going to walk you through some common mistakes that Brazilian English speakers are prone to.
Source language (Portuguese) => seu / sua
Target language (English) => your / his / her
I would say that you must stick to these 2 fundamental rules.
Question #1: To whom are you referring to?
Answer: someone in a 2-way conversation.
Question #2: To whom are you referring to?
Answer: someone in a 3-way conversation - referring to the 3rd person in the conversation.
