[Grammar] to see you or to seeing you

[Oceanlike]

I thought I should use ‘base verb’ after ‘to’.
Please help me to understand why the correct answer to the question below is to “seeing” you there instead of to “see” you there.

Question: Are you going to the movie tonight? I look forward to seeing you there.


Thank you!

"Seeing" is a gerund (noun). It is the object of the preposition "to". In this case "to" is not an infinitive marker. That is why "see" doesn't work.

There are a few other cases like this- we are accustomed to seeing someone, and phrasal verbs with two particles, where the second is to as in your example, take -ing.

How can I find the whole list of such phrasal verbs? Any suggestions how to google it?

I think 'Someone has taken to seeing someone else' is another example, but I am not a teacher.
