What is important for or to?
3 Answers. The simple explanation is that "important to" is something you value, while "important for" is something you need, or that will help you in some way. A nice example is: "It is important for you to get well" ~ your life will be improved by returning to health.
Is essential to doing or to do?
I distinguish three different constructions using essential: to be essential to something (= to be an essential part (the essence) of something) to be essential to do something (= to be very important to do something)
When should I use used to do and when should I use be used to doing?
It is a special structure. We use the structure used to do for the past only. If I say "I used to smoke" it is like saying "I smoked in the past but I don't smoke now." Do not confuse used to do with the expression be used to.
How important gerund or infinitive?
In the following sentences, gerunds sound more natural and would be more common in everyday English. Infinitives emphasize the possibility or potential for something and sound more philosophical. As a rule of thumb a gerund is best most of the time. Learning is important.
