Namskar teacher, I want to know the difference between
infinitive 'to' and Without "to" does it change the meaning of the sentence.
i.e i want to talk to you.
I want talk to You.

Hello rameshwaraavhad,

The question of whether to use to + infinitive or the infinitive without to is really a question about the verb which comes before. Some verbs are followed by to + infinitive and other by the infinitive without to. For example, 'want' is followed by to + infinitive and so your second example is not grammatically correct.

I'm afraid there is no rule to tell you which verbs are followed by which form. You simply have to learn this with each verb. For example:

want + to infinitive

try + to infinitive

allow SB + to infinitive

 

let SB + infinitive without to

make + SB + infinitive without to

why don't you suggest me the correct template of the letter writing, why do ask me to search in other website. the purpose of this site is to help the people like me then why you

Hello paparna1986,

The purpose of this site is to provide high-quality materials for self-study. Where possible, we provide support for users who are using those materials by explaining aspects which are unclear and providing help with the broader language system. In other words, the LearnEnglish Team is here to help users with our materials, not to provide individual courses or to act as individual teachers for our users.

 

There are no templates on our site. This is not the kind of material that we have available. Therefore, Kirk gave you the most helpful suggestion he could.

 

If you require someone to produce templates for you on demand then you will need to hire a teacher to work with you. That is not our role. We offer, free of charge, a range of materials to help you improve your English and we will help you to use these materials if you have problems. We do not write new materials upon demand, however.

 

Best wishes,

can you please guide me the format of the a leave letter to the principal of the school and format of the letter to any office regarding complaining about some issue. and also the format for the letter to write an application for any job

Hello paparna1986,

I'd suggest you do an internet search for 'template leave request letter', 'template letter of complaint' and 'template job application cover letter'. I'm sure you'll find many good examples out there. I'd recommend looking at a few of each and then choosing the one that looks best for your needs.

All the best,

are these sentences ' I am made to do' or you will make me to learn' correct

Hello paparna1986,

The first sentence may be correct but appears incomplete: something should probably follow 'do', depending on the context. 'I am made to do this', for example, or 'I am made to do this task, even though I do not want to.'

The second sentence is incorrect.
