Verbal Ability - Sentence Improvement - Discussion

In English, the form V + -ing is called a gerund if it serves as a noun. For example, the gerund form of "run" is "running". (I like cats, I like dogs, I like running). However, not all V + ing forms are gerunds--in "I am running", "running" is another verb.

1) If the to is part of a phrasal verb or verb + preposition combination:

A phrasal verb is something like "look forward to", "confess to", etc. In this case, the "to" is part of the verb itself.

Some examples are:

I am looking forward to attending the party. I am committed to supporting the Linguistics proposal on Area51.

2) If the to is part of an adjective + preposition combination:

For example:

A lot of women aren't accustomed to being treated so well! I am opposed to increasing taxes.

These look similar to the examples above, but you can tell that a word like accustomed is an adjective in this case because there is a form of the verb to be. That is, you are an adjective.

3) If the to is part of a noun + preposition combination:.

For example:

His addiction to gambling has caused a lot of stress for his family. Her great dedication to teaching inspires her students.

The word "to" in this phrase is slightly confusing because it is usually used to introduce a verb, as in "want to" or "have to". However, "look forward to" follows a different pattern:

I look forward to [a thing you would like to happen; a noun]

Obviously, "hear" is not a thing, so it wouldn’t make much sense to "look forward to hear from you". The thing you are looking forward to is "hearing from you":

[correct]: I look forward to hearing from you.
[wrong]: I look forward to hear from you.

[correct]: I am looking forward to hearing from you.
[wrong]: I am looking forward to hear from you.

The reason is that "to" is just a preposition here and has nothing to do with the infinitive, just like in "listen to" - you would say "I listen to singing" rather than "I listen to sing", wouldn’t you?

In grammer, "to hearing" is incorrect because we can not put verb+ing if the word start with "To" it means INFINITY and verb + ing mean gerund so both cannot come together. Example "TO developing India" is wrong and To develop India is absolutely correct. Another example " To smoke is injurious to health" and "Smoking is injurious to health".

I think that hearing is not the correct word, infact none of the words suit the sentence correctly. I suggest I request you to please explain how "hearing" was choose as the correct word.

I think the sentence needs no correction.

"We look forward to hear from you", seems correct as we look forward to hearing from you is absolutely wrong.

Hearing means "The act of hearing attentively".

Ex: "they make good music--you should give them a hearing".

So we can use hearing here.

When to is used as a preposition, it is followed by an 'ing' form:

I want to see you./incorrect.

I look forward to seeing you./correct.

Here 'to' is a proposition and 'hearing' is a noun. This structure 'to+ing' is known as gerund. Hence given one is correct.

to hear can be replaced with hearing. replacing with only hear seems wrong
--------We look forward hearing from you
