BBC Learning English – 3 mistakes you make with prepositions

3 mistakes you make with prepositions.
1). I look forward to see you tomorrow.
The rule is that after preposition, we can use a gerund a noun or a clause.
So because it comes after the preposition “to” , we need to change “see” to the gerund, “eeing”
I look forward to seeing you tomorrow. I look forward to meeting you tomorrow.
I look forward to speaking with you tomorrow.
2). Sorry for late. So we could use the rule. We’ve just talked about and put a gerund after the preposition “for”. Sorry for being late, but native speakers more naturally, simply say, “Sorry, I’m late.” with no preposition.
3). It depends of the situation. The problem here is the preposition of. It should be on. It depends on the situation
