Singular Indefinite Pronouns

Raj asks:
Can a sentence start with a word “each”

For example, Each column was filled with pebbles.

Yes. “Each” is what we call a “singular indefinite pronoun.” Other such pronouns are:
another
any
anybody
anyone
everybody
everyone
much
nobody
no one
nothing
somebody
someone
something

You can start a sentence with any of these:
Each of the students was prepared.
Any of the students could solve this problem.
Much depends on your success.

I'll try to post a longer item soon on indefinite pronouns. They can pose a lot of problems.

I'd say 'each' is a determiner, not a pronoun. But even if you call it a pronoun, why 'indefinite'?

An indefinite pronoun does not refer to a SPECIFIC entity.

Of course, in the above example, "Each column...", "each" is an adjective.

Well, what does 'singular indefinite pronoun' mean? 'cause there's also 'plural indefinite pronoun'.
