whtizaUsing they/them pronouns is confusing and difficult to read because one always thinks of a plurality of people. Why not just pick new words to use?
-RJ-Person 1: Is your friend Bob coming over? Person 2: No, they can’t make it, they’re busy
One Bob, and we all know it’s one Bob, no confusion. Look for context. It’s not that hard.
Person 1: Are Bob and Janice coming over? Person 2: They can’t make it.
Sometimes additional context is needed.
Bob said he’s coming, but Janice said they can’t make it.
Bad example. Having the ‘but’ in there introduces ambiguity. We can’t tell if Janice is contradicting Bob and saying they both won’t be coming, or if it’s just Janice speaking for themself.
When already using the specific identifier of names, using general identifiers isn’t needed, and is rarely done. Most people would just say Bob is coming but Janice can’t make it.
DevccoonYour example is unambiguously plural. It’s not a good illustration of “they” creating confusion.
Person 1: Are Bob and Janice coming over? Person 2: They can’t make it.
Alternative:
Person 1: Are Alice and Janice coming over? Person 2: She can’t make it.
Alternative:
Person 1: Are Alice and Janice coming over? Person 2: Alice can’t make it.
This is far less ambiguous than you’re trying to force it to be.
The original makes sense. Both your alternatives are weird. The first is completely strange the second one begs the question, what about Janice.
