I came across the following sentence:
Mon père pense que les jeunes passent trop de temps en ligne mais je ne suis pas tout à fait d'accord avec il.
Now the word "il" refers to "père." So my question is what is the name of this kind of pronoun. Is it a subject pronoun or is it a direct pronoun? Because were it a direct pronoun we should have used le instead of il. Also is there a way to determine which pronoun to use in general? Thank you.
