- What you said could be OK, but accoding to who /to whom?
I know it could be an informal speech, but I would like to ask if I must use 'who' or 'whom' in the sentence.
If you want to be like the vast majority of native speakers, you will forget that the word "whom" exists.
If you want to be absolutely grammatically correct, then use "whom" there. It is an object of the preposition "to." Use "whom" for objects, "who" for subjects.
