Could you please tell me whether I can use "they" instead of "he or she" in the following sentence?
Every individual person has to know how much they want to spend.
The use of "they" as a gender-neutral, third-person singular pronoun is in wide use, and has been for decades.
However, there are still purists who frown on using "they" for a single subject. Some might mark you as incorrect on a test.
You can rewrite: Individuals should know how much they want to spend.
In my book they/them are listed as personal pronouns. (subjective/objective)
Merriam-Webster's Dictionary says: pronoun, plural in construction.
What books are these purists reading? Beano?
Merriam-Webster's also has:
13th century Those are a lot of decades!
