This question already has an answer here:
Lately, I've been trying to understand the use of pronoun agreement in depth. While in the process I came across this website.
According to the Author:
Professional writers might revise the sentence so that a pronoun is unnecessary. Sometimes, they make the antecedent plural so that they can use the natural-sounding they, them, or their. Or they might decide to alternate he and she in the piece so that both genders get mentioned.
Using he or she or him or her is technically correct. But it's also bad style. Avoid these constructions if you can.
In the case of following example, what are ways you could avoid using his or her pronoun?
Everyone should take his or her seat.
I am beginner with English grammar, so it would be great if you explain it with clear and simple examples. Also please feel free to demonstrate with your own examples and share your tips.
