I am looking forward to (meet / meeting)? you

"I am looking forward to meeting you" Is the correct answer.

The verb is 'to look forward to' = 'to anticipate' (transitive = requires a direct object).

So, the direct object should be the gerund (noun) form of the verb 'to meet', i.e. meeting.

In contrast: "I'm waiting to meet you".

The actual problem in this case is, that "to" is a preposition here and NOT part of the infinitive! Therefore the Gerund is required.

After verb+preposition, only the Gerund can be used:

I'm fond of doing sports. I'm looking forward to seeing you. 

After some verbs, there's only the infinitive with to that can be used:

I wanted to see you. 
-> Here, "to" is

Only #2 is correct. The phrasal verb 'look forward to' must be followed by a noun or, as in this case, a gerund, which is a noun equivalent.

Most learners get confused by the infinitive to, thinking that after “to” the bare form of the verb must be followed. In fact, it's the opposite. A structure with looking forward to is always followed by a direct object (noun or gerund).

1. I am looking forward t

The expression look forward to + ing (and others formed in the same way) often cause learners confusion, because, when studying gerunds and infinitives, they learn that the word to is usually followed by an infinitive:

• I want to go.
• I need to see y
