I have doubt because I know that the type of a verb is "to+ infinity" there is no the enhancement of the -ing that transforms it to come to be a noun.

This is a really common mistake!So, don"t worry. Below is the cure.

You are watching: I look forward to hear or hearing

Ask yourself which one makes an ext sense: "look forward to it" or "look forward to execute it"?

Chances are you recognize that "look front to it" sounds much more natural, due to the fact that you"ve viewed or you"ve heard others usage it that method before. And, yes, with look front to, you need hearing from you (NOT hear indigenous you).

Grammar points

The trick is to remember that to can be either the infinitive marker or a preposition1.

You require a verb ~ the infinitive marker to (e.g. I desire to swimming this evening).You require a noun after a preposition (e.g. She went ago to the pool.)

It doesn"t have to be a actual noun, simply something that attributes like a noun. In other words, it"s the thing of a preposition, together it"s traditionally called; or as identified a little an ext precisely (same link):

The prepositional complement is commonly a noun phrase, however it may also be a nominal loved one clause or one -ing clause. Both the nominal relative clause and the -ing clause have a range of functions similar to that of a noun phrase: ...(emphasis mine)

In your example, to in look forward to is a preposition. Why? due to the fact that you have the right to say look front to something (e.g. He had worked hard and also was looking front to his retirement.) In other words, speak "I"m looking forward to it" makes sense.

And that makes you need a noun or miscsmashville247.netaneous noun-like, i.e., hearing, not hear:I look/"m looking front to hearing from you.

1When the preposition to is provided in a unit volume verb, some people call it a particle, yet let"s save this post simple and use just the term "infinitive marker" and "preposition".) here is a perform of together phrasal verbs (ending through to). Some common ones, in mine opinion, room look forward to and also be offered to. Another common unit volume verb (but no on the page) is object to.

Bonus

Here is a associated mistake which share the same reason of confusion: used to vs. be supplied to.

Remembering this might be helpful:

He used to live in Frankfurt, but he"s not used to living in cold weather.

The very first to is the infinitive marker to. The 2nd to is a preposition.The an initial to is about "He offered to do something".The 2nd to is about "He"s not supplied to something".
