I have actually doubt due to the fact that I recognize that the form of a verb is "to+ infinity" without the addition of the -ing that transforms it to come to be a noun.
This is a an extremely common mistake!So, don"t worry. Here is the cure.
You are watching: Look forward to hear or hearing
Ask you yourself which one makes an ext sense: "look front to it" or "look forward to carry out it"?
Chances are you understand that "look front to it" sounds an ext natural, because you"ve seen or you"ve heard others usage it that way before. And, yes, v look front to, you require hearing native you (NOT hear indigenous you).
The cheat is to remember the to can be one of two people the infinitive marker or a preposition1.
You need a verb after ~ the infinitive marker to (e.g. I desire to swimming this evening).You need a noun ~ a preposition (e.g. She went earlier to the pool.)
It doesn"t have to be a genuine noun, just something that functions like a noun. In other words, it"s the object of a preposition, as it"s traditionally called; or as characterized a little an ext precisely (same link):
The prepositional complement is frequently a noun phrase, but it may likewise be a nominal relative clause or one -ing clause. Both the nominal family member clause and also 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 can say look front to something (e.g. He had functioned hard and also was looking forward to his retirement.) In various other words, speak "I"m looking forward to it" makes sense.
And that makes you need a noun or something noun-like, i.e., hearing, no hear:I look/"m looking front to hearing indigenous you.
1When the preposition to is offered in a phrasal verb, some people call that a particle, yet let"s save this post an easy and use only the ax "infinitive marker" and also "preposition".) below is a list of together phrasal verb (ending with to). Some common ones, in mine opinion, are look front to and also be used to. Another common paragraph verb (but no on the page) is object to.
Here is a associated mistake which shares the same cause of confusion: used to vs. be provided to.
