Old English grammar books indicate a general rule of thumb for who vs whom -
- Who should be used to refer to the subject of a sentence.
- Whom should be used to refer to the object of a verb or preposition
Many people have raised similar questions in this forum and most have been answered, including this good example who vs whom. which one is appropriate.
However, I feel that my question could not be fully answered by either the conventional grammar book (not looking hard enough) or the posts in this forum. Hence this question below.
According to this link pronoun mistake #3, whom should be used. Can who be used in this example (seems strange)? If not, is whom used as a subject or an object?
The link above discussed the following example -
Huffington post had the following paragraph (date unknown) -
On New Year’s Eve at 11:45 am, Pope Francis called up the small community of the Carmelite nuns of Lucena in Cordoba, Spain, but they didn’t pick up the phone. Their once-large community has now dwindled to a mere five nuns, three of which are from Argentina, which is also the pope’s home country.
I interpreted the which here refers to the subject - the nuns, who are from Argentina. Is it correct that nuns are considered a "subject", not an "object"?
The author of the link (not of the Huffington post article) thought whom should be used, instead of which. Does this mean whom can be used as a subject of a sentence?
