What is Their Main Difference?
Uses and Comparison
We tend to use both future simple to talk about predictions and guesses about the future. The same case goes with future continuous tense. We tend to make guesses about situations that we are uncertain about.
Here, we are forecasting a future event.
Here, we are guessing about a future events.
2. Spontaneous Decisions
We tend to use will to talk about decisions for the future made on the spot and right now. Pay attention that decision is being made at the moment of speaking.
Here, we are talking about a decision made on the spot to do something in the near future.
will be opening the door.
Here, we are talking about a fixed event in the future.
3. Fixed Arrangements
When we want to talk about arrangements about the future, we use future continuous tense. In this case, we are trying to review or remind an event.
Here, we are referring to a fixed event.
will join the meeting at 10 o'clock.
Here, there is a uncertainty in the chance of occurrence.
4. Ongoing Actions
There are times when we want to talk about an unfinished action or event which will be continuing to some time in the future. In this case, we will be using the future continuous tense.
Here, we are talking about an ongoing action in the future.
will work at 10:30 tomorrow.
This example is not referring an ongoing action in the future. It is referring to a premade plan about the future.
We can also use the 'will' tense in interrogative form to request something or make an offer. We tend to use interrogative mood to make the offer and request sound more polite.
Here, we are politely requesting something.
Here, we are not making an offer, we are making a suggestion.
Now that we have talked about the uses of tenses and compared them, we can talk about their structures individually.
1. Future with Will
In order to create future with will, 'will' is added to the subject of the sentence followed by the base form of the main verb.
