Relative pronouns

The main difference is that there are no "contact clauses" in It. but the pronoun is always expressed, so "the man I love" is "l'uomo che amo".

Other differences:

"what" "ciņ che". "Dimmi ciņ che sai sull'incidente" ( Tell me what you know about the accident).

"all (that)" "tutto ciņ che". "Dimmi tutto ciņ che sai sull'incidente" ( Tell me all you know about the accident).
