Question

each of them followed their plan .Correct the determiner?​

Answer 1

Answer:

The traditional grammar-book answer is that “each of them” is singular, and therefore we need a singular pronoun: “Each of them followed his plan.”

Then, grammar books decided that some people are female, so they conceded that “Each of them followed his or her plan” was correct.

Then common sense began to prevail, and the “singular they” came into use (or rather, its overwhelming use by actual speakers of English began to be acknowledged), and so many publications (and teachers) are gradually recognizing that the most sensible sentence is as you wrote it:

“Each of them followed their plan.” (or how about “Each of them followed their own plan.”

This makes preeminent sense, since “each of them” is NOT a single person, but a group of people! There is not one plan belonging to him, but many plans, belonging to them.

The grammar of “Each of them followed his plan” has always been awkward and even ambiguous—was there one guy whose plan all the others followed? (“Each of them followed Tom’s plan”? )

See, “their” just works better. And life goes on.
