Writing: Pronoun clarity — Basic example

after practicing the violin together for 15 years Justine told Katie that she was the better violinist alright so immediately when I read that when they say that she was a better violinist I don't know it's Justine talking about she Justine or is Justine talking about she K T so this pronoun she who's it referring to is it referring to Katie or is it referring to Justine it could be either one it Justine could say be saying that Justine is better or she could be saying that Katie is better the way it's written you do not know and which kind of makes the sentence fairly meaningless so I definitely don't want to keep it the way it is so what I would want is some clarity on who was the better violinist so what I like about this second choice is it makes it very clear that Katie was the better violinist so let's read that after practicing the violin together for 15 years Justine told Katie that Katie was the better violinist yep I definitely like it now you might say oh you know look I'm using the Katie twice and three words in the sentence isn't that redundant and it might feel that way but you really do need to use Katie twice in order to make sure that you understand that Justine thinks that Katie was the better violinist so this needs to be Katie right over here if you don't do that you don't know who Justine is talking about and then the other choices let's see after practicing the violin together for 15 years Justine told Katie that she's was the best better right well this one this one is just you know it's not this one is ambiguous this was just grammatically incorrect you're having you're having a possessive pronoun here what are you possessing so definitely rule that one out and then after practicing the violin together for 15 years Justine told Katie that they were the better violinist well they were the that that's not making sense saying that they were both but it's making a comparison to whom I don't know they could say Justine told Katie that they were both good violinists that would have been an okay statement but that's not what they're saying then we're making it comparison on who is a better violinist so this doesn't make sense either
