warning The "To" Trap!

Is "to" an infinitive or a preposition?

(កុំច្រឡំ! ពាក្យ "to" ក្នុងកន្សោមពាក្យមួយចំនួនគឺជាធ្នាក់ ដូច្នេះវាត្រូវបន្តដោយ V-ing ជានិច្ច!)
I look forward to see you. ❌
(Here, "to" is a preposition, so it needs a noun/gerund.)
I look forward to seeing you. ✅
(Correct. Other examples: "used to doing", "object to going".)

Teacher, what is the difference between "I used to wake up early" and "I am used to waking up early"?

Hi Makara! This is a very common C1 trap!

"I used to wake up" means it was a habit in the past, but you DON'T do it anymore.
"I am used to waking up" means it is normal/comfortable for you NOW. Here, "to" is a preposition, so it must be followed by a gerund (-ing)! 💡
