(A proofreader's note regarding “who” and “whom”)

Words “who” and “whom” are pronouns both

That dress alike apart from hem.

Yet clothing fails to tell us who

Hath right of place when phrases aim.

One serves as subject, acting out,

The other, object—acted on.

Think “who” might shout and dash about

Regardless “whom” imposed upon.

To know if subject pronoun is,

Try “he” or “she” to substitute.

Its nature true may object be

If “him” or “her” doth  better suit.

Thus relative pronouns “who” and “whom”

As subject/object serve in clauses.

Sometimes a clause itself is subject;

Analysis then is cause for pauses.

But “whom” is choice for after “to,”

As is with prepositions most,

Which lead to object in the phrase

And hold that role to baldly boast.

Though language changes over time

And fashion cycles ever more,

The hem of “whom” remains the same,

While “who” advances to the fore.

“The man who came was one with whom

Most girls would flirt and, maybe, swoon.

And, yet, there were a few for whom

The day could never end too soon.”
