Hello Swiss Jake,
Are you a German-speaking Swiss? If yes, then this should help a bit:
'Whom' is used in the accusative case, which is very obvious in German
inflections but only seen in English prounouns, e.g. him, her, us, and
whom.
However, where in German there are two distinctive cases, accusative
and dative, in Modern English there's only one case, which comprises
both the accusative and the dative. This case is called objective.
So have a look at the following sentences:
a. I saw the man
who won the prize.
(German:
Ich habe den Mann gesehen der den Preis gewonnen hat.)
'who' in this relative clause is the subject of the verb
won, so the
nominative case is required, just as it is clearly seen in German.
b. He is the man
whom I admire.
(German:
Er ist der Mann den ich bewundere.)
Here 'whom' is the object of the verb
admire, therefore the
objective case is required. Compare the Accusative
den in German.
Hope this helps.
