looking forward to 의 to는 전치사

"to" is followed by the base form of a verb (infinitive),

as in "to go," "to eat," "to study," etc.

However, in "I am looking forward to hearing from you soon,"

the verb "hearing" is in the -ing form after "to."

 

Why?

This happens because "look forward to" is a phrasal verb where "to" is actually a preposition, not part of an infinitive.

 

Rule:

When a preposition (like "to," "at," "in," "on," etc.) is followed by a verb,

the verb must be in the -ing form (gerund).

 

 

✅ Correct Examples:

• I am looking forward to meeting you.
• He is used to driving long distances.
• She is committed to helping others.

❌ Incorrect Examples:

• ❌ I am looking forward to hear from you. (Wrong)
• ❌ He is used to drive long distances. (Wrong)

So in "looking forward to", the "to" is a preposition, 여기서 to 는 전치사야

not an infinitive(부정사) marker, which is why it must be followed by a gerund(동명사 (-ing form)).**
