Correct version: I am used to playing cricket in my spare time.  Meaning: I am accustomed to playing cricket in my spare time.  (i.e. I play cricket in my spare time now.) Are these interrogatives of above sentences correct? No 1: Do I used to play cricket in my spare time? Did I use to play ...? 2: Am I used to play cricket in my spare time? Am I used to playing ...?

Question 1: Yankee said: 1: Do I used to play cricket in my spare time? Did I use to play ...? As far as I know, 'did (not) ... use to' is still considered to be the correct form in negative and interrogative sentences.  However, I'm also aware that some people disagree with this. There is a usage note here that supports my view: http://www.bartleby.com/64/C001/065.html   Question 2: Both Philip and Yankee said: I am used to playing cricket in my spare time.  I was told that after to simple Present Tense form is used but playing is not simple Present Tense form of play. What would you say on this?  Most of the time you will find the base form (infinitive) of the verb after the word 'to'.  However, certain expressions require the '-ing form'.  Some examples of these are: - be used to doing - be accustomed to doing - look forward to doing - admit to doing - object to doing   Question 3: 1: I used to play cricket in my spare time. I did this regularly in the past, but don't do it now.. 2: I was used to playing cricket in my spare time.  Playing cricket in my spare time didn't feel unusual to me because I did it often. What is difference between the meaning of above sentences?

Hi Jeka

A source of confusion with the "preposition explanation" is that many dictionaries also call the word 'to' a preposition when it is used to indicate the infinitve.  For example:

"to
preposition
1 used before a verb to show that it is in the infinitive"
Cambridge Dictionary

Webster's and the American Heritage Dictionary have similar entries.

On the other hand, the OED has a category called "infinitive marker" (rather than 'preposition') for this use of 'to'.
OED

Definition of preposition in Merriam-Webster's Collegiate Dictionary:

a function word that typically combines with a noun phrase to form a phrase which usu. expresses a modification or predication.

Please explain me above definition with the help of an example. Is preposition always followed by noun/pronoun?

 

Definition of to in Merriam-Webster's Collegiate Dictionary:

¹to: 8 - used as a function word to indicate that the following verb is an infinitive <wants to go> and often used by itself at the end of a clause in place of an infinitive suggested by the preceding context.

How can it be differentiated that whether to is being used as preposition or infinitive in a certain sentence?
