Can I use 'he' in this sentence? John and Emma live in London. He is single. OR John and Emma live in London. John is single. For me it sounds very inaccurate to refer to John by using subject pronoun he. I had a discussion about this with my spanish friend and I was very doubtful if it's allowed to use 'he' in that sentence. I tried to find a grammar rule which would prove that, but I didn't find anything. So, what's the truth?How about these sentences? John and Emma live in London. HE is single and SHE is married. IMO the latter sentence wouldn't be very often used in spoken language. Atleast I would use names instead of subject pronouns in both of the cases.
