In the sentence, "I want to play cricket", is "cricket" an object of "to play"? Can to-infinitives have objects as transitive verbs have?

Similarly, can to-infinitives be used as objects of transitive verbs? For example, in the sentence, "We want to play", is "to play" an object of the verb "want"?

Hi Adya's,

Yes, the infinitive can take an object and can be an object, just as your examples show. Well done!


Hello vannak,

I'm afraid we don't provide answers for questions from elsewhere. It's not our role to do people's homework or tests for them!

Thank you for your lessons. I have a question:

Why we use gerund "getting" after "to" in the following sentence?
They are more welcoming to getting help from specialists.

Hello N-G,

The word 'to' can be used in different ways. Often it is part of an infinitive (e.g. 'to go', 'to get'), but other times, like in the sentence you ask about, it is a preposition. When we use a verb after a preposition, it goes in the gerund form, which is why 'getting' is correct here.

All the best,

How can I recognize where "to" is a preposition?
For example, my sentence is similar to the below sentence.
It’s easy to play the piano.
In both of them there is an adjective before "to".

Hello N-G,

You have to look at the words that surround 'to'. If there is a base form of the verb (e.g. 'be', 'go', 'eat', 'sleep') after 'to', it's most likely an infinitive. If there is an -ing form (e.g. 'being', 'going', etc.) it's probably a preposition.

It's also useful to learn common structures that infinitives are used in. For example 'It's' + adjective + infinitive is a very common structure, and is what is used in your sentence about the piano.

I hope this helps you.

All the best,

1.we say "I'm on my way to work" but
which is the correct one form these? can we use a verb?
I'm on my way to go home" or "I'm on my way to home"

2. can we use "As" like this ? The characteristics of protons are as given as below

Hello raj jk,

1. 'to' is used with words to indicate direction, but isn't used before the word 'home' -- this is an exception to the general rule. So the correct form is 'I'm on my way home'. With other words, you should use 'to', e.g. 'on my way to school', 'on my way to your house', 'on my way to class', etc.

2. I have found examples of 'as given as below' in a quick internet search, but I'd recommend saying '... are as given below', i.e. I wouldn't repeat the 'as' before 'below'.

All the best,
