If you use a verb after 'want' ( saying what you want to DO), this needs to be an infinitive with 'to'. For example: I want to go home. I want to see this film. I want to be a journalist. You cannot say 'I want go', 'I want see' or 'I want be' - all of these are wrong. If you have a noun after 'want' (saying what you want to HAVE), you don't use 'to'. For example: I want a break. I want orange juice. I want more money. I want some advice. Does that make sense? ................................................. NB The only time that you'll come across a verb in a different form after 'want' is in colloquial English where 'want' means 'require'. For example 'My car wants washing' ( More unusually, in non-standard 'dialect' in Scotland and Ireland and a few parts of N. America, you might even hear 'My car wants washed'). I wouldn't worry about either of these idiomatic uses, though.

Another instance in which you cannot use TO immediately after want is when you want somebody else to do something . For example, I want HIM to come with me

After want you are compelled to use to
