When to Use Future Simple

-
Spontaneous Decisions
Use the Future Simple for decisions made at the moment. This is perfect when you decide something on the spot.
Example: “I’ll take care of it!” or “I’ll get the door.”
-
Predictions
The Future Simple is useful for predictions based on general knowledge or opinions, rather than concrete evidence.
Example: “It will probably rain tomorrow.” / “I think she will win the race.”
-
Promises, Offers, and Suggestions
When making a promise or offering help, the Future Simple helps convey a sense of sincerity.
Example: “I’ll be there on time, I promise.” / “I’ll help you with your homework.”
-
Polite suggestions or offers
Additionally, ‘shall’ is often used for polite suggestions or offers, especially with “we.”
Example: “Shall we go to the park?”
