Infinitive with to (Examples: to go, to speak)

The infinitive of a verb has two forms: the to-infinitive and the infinitive without to. 

The to-form consists of to + the base form of the verb:

• I want to speak to you.
• We came to Almubarok to study, not to play. 

Used in many kinds of sentence. After:

I'm sorry                                                     I'm sorry to trouble you
something                                                  Would you like something to drink?
nothing                                                      There's nothing to worry
anything                                                    Have you got anything to eat?

Also used after many verbs:

have                                                          You have to go now
hope                                                          I hope to see you soon
want                                                          I don't want to talk about it
would like                                                 Would you like to follow me?
would you love                                         I'd love to stay a bit longer

And used to say why we do things:
                                    Why did you open this blog?  'To read it'


We use the to-infinitive after a number of common main verbs:

agree   aim   arrange   ask   begin   choose   continue   claim   decide   demand   fail    forget
hate   help   hope   intend   long   love   like   learn   manage   mean   need   offer   prefer  
prepare   pretend    plan   promise   propose   refuse   remember   try   want   wish

• We agreed to go to Bandung for our rihlah (tour).
• Mr. Abdee asked us to call in the manager on his way to work.
• Did you remember to post your tasks on the fb group?.
• She just wants everybody to be happy.

Some of these verbs are also often followed by -ing.

We can use the to-infinitive in a clause with a verb that has no subject (a non-finite clause). The to-infinitive focuses on the idea of an action or the results of an action, rather than the action in itself:

• To work in a big company had always been her ambition.
• To get there before sunset prayer's time, you would have to take the six o’clock bus.

We don’t use the infinitive (with or without to) after prepositions:

I would like to be thankful for reading my web.

Not: … I would like to be thankful for read … or … for to read … my web.
