All human life is a matter of decisions. philosophically speaking, it is like asking or showing the way. Decisions are reflected in English grammar in three ways that I know:
First: "will" for spontaneous or instant decisions
I am hungry I'll get a sandwich.
I am cold I'll get a pullover.
second: "going to" for planned decisions
I am going to see the film this evening.
Third: present continuous for decisons already taken: we are having a party on Saturday.
Could anybody add something with regards to English grammar and vocabulary.
The present simple is sometimes used for decisions:
When she arrives, we leave.
This is, however, just replacing 'we're leaving'.
