What’s the difference? ‘Will’ and ‘be going to’

Will + infinitive Be going to + infinitive
A decision at the moment of speaking:

Julie: There’s no milk.
John: Really? In that case, I’ll go and get some.

A decision before the moment of speaking:

Julie: There’s no milk.
John: I know. I’m going to go and get some when this TV programme finishes.

A prediction based on opinion:

I think the Conservatives will win the next election.

A prediction based on something we can see (or hear) now:

The Conservatives are going to win the election. They already have most of the votes.

A future fact:

The sun will rise tomorrow.

For promises / requests / refusals / offers:

I’ll help you tomorrow if you like.

More examples:

    • (The phone rings)
      Julie: I‘ll get it!
      (‘I’m going to get it’ is very strange because it makes us think that Julie knew the phone was going to ring before it did).


  • I‘m going to go on holiday next week.
    (‘I’ll go on holiday next week’ makes it sound like you’ve only just decided at that minute. Of course, this is possible, but normally we plan our holidays more in advance!).

Other points about the future:

We use the present continuous tense for definite future arrangements. Often, it doesn’t really matter if we choose ‘be going to’ or the present continuous. In the following example, there is really very little difference in meaning:

  • I‘m going to the cinema tonight.
  • I‘m going to go to the cinema tonight.

We use the present simple tense in two cases. First, we use it for a timetabled event in the future, like public transport or the start of a class:

  • My train leaves at six tonight.
  • His class starts at 9 am tomorrow.

Second, we use it after certain words, when the sentence has a future meaning. These words are: before / after / as soon as / until / when:

  • I’ll call you when I get home.
  • She’s going to study after she finishes dinner.
  • Please drink some water as soon as you complete the race.


Prepositions are short words (on, in, to) that usually stand in front of nouns (sometimes also in front of gerund verbs).

Even advanced learners of English find prepositions difficult, as a 1:1 translation is usually not possible. One preposition in your native language might have several translations depending on the situation.

There are hardly any rules as to when to use which preposition. The only way to learn prepositions is looking them up in a dictionary, reading a lot in English (literature) and learning useful phrases off by heart (study tips).

The following table contains rules for some of the most frequently used prepositions in English:

Exercises on Prepositions

Difference Between Going to and Will


Going to and Will

“Going to” and “will” are used in the English language as the future tense. The future tense has many different ways of being expressed. Different forms include the simple future tense, “going to form, be about to form,” and the future continuous tense, future perfect tense, and future perfect continuous tense.

“Going to” and “will” are used for the simple future tense, but their usages are different from each other. Let’s try to understand them by some examples and explanations.

Simple future tense


The simple future tense is used in the English language to tell about things that cannot be controlled. The simple future tense is used to express the future as a fact. For example, It will be Christmas in a week.
We also use this tense to express our belief about the future and what we think might happen in the future. For example:

I think the U.S. is going to win the soccer match.

While talking about what we think might happen in the future, we also use words like; I believe, probably, expect, I am sure, I think, etc. For example:

I believe I will go for a movie today.

I will probably go for a movie today.

We also use this tense when we decide at the time of speaking that something has to be done. For example:

It is raining. I will tell mom to take an umbrella.

Going to form

“Going to” is used when we have decided to do something before talking about it. For example:

“Why do you want to sell your car?”

“I am going to buy an SUV.”

The main thing to remember in the “going to” form is that the decision should have been made before talking about it and all the preparations made to do the act. It is important to remember that in such cases when decisions have already been made, the simple future tense with “will” should not be used.

The “going to” form is also used to talk about something going to happen in the future or likely to happen in the future with certainty depending upon the present. For example:

It is definitely going to rain; look at the black clouds in the sky.

This form is also used to express an action at the point of it happening. For example:

Get in the car, it is going to rain.


1.“Will” and “going to” are both used for the future tense. “Will” is used in the simple future tense where the decision is immediate; whereas the “going to” form is a separate form which is not used for the simple future tense.
2.“Will” is used to express the future as a fact. It is used to express what we think might happen in the future and when we decide at the time of speaking that something has to be done in the future. Whereas the “going to” form is used for a decision that has been taken before speaking for something which is likely to happen for sure in the future and to express an action at the point of happening.



What are conjunctions?

A conjunction is a part of speech that joins two words, phrases or clauses together.

There are three types of conjunctions:

Coordinating Conjunctions Correlative Conjunctions Common Subordinating Conjunctions
  • for
  • and
  • nor
  • but
  • or
  • yet
  • so
  • either…or
  • neither…nor
  • not only…but also
  • both…and
  • whether…or
  • after
  • before
  • although
  • though
  • even though
  • as much as
  • as long as
  • as soon as
  • because
  • since
  • so that
  • in order that
  • if
  • lest
  • even if
  • that
  • unless
  • until
  • when
  • where
  • whether
  • while

Coordinating conjunctions

Coordinating conjunctions, also called coordinators, are conjunctions that connect two or more equal items.


  • He plays tennis and soccer
  • He works quickly but accurately
  • You’d better do your homework, or you’ll get a terrible grade.

Correlative conjunctions

Correlative conjunctions are used in pairs.They work in pairs to coordinate two items. Examples of correlative conjunctions include both…and…, either…or, not only… but also…


  • I didn’t know that she can neither read nor write.
  • You can either walk to school or take the bus.
  • Both Sara and James are invited to the party.
  • Whether you watch TV or do your homework is your decision.
  • Not only are they noisy but they are also lazy.

Subordinating conjunctions

Subordinating conjunctions, also called subordinators, are conjunctions that join a dependent (or subordinating) clause to an independent (or main) clause.


  • He reads the newspapers after he finishes work.
  • Even if you get the best grade in the writing test, you’ll need to pass an oral test.
  • Although he is very old, he goes jogging every morning.
  • She didn’t go to school because she was ill.
  • They went to bed since it was late
  • As soon as the teacher had arrived, they started work.

“So”, subordinating conjunction or coordinator?

So” is a small English word that can have different meanings. As mentioned in the table above, it is commonly used as a coordinator rather than as a subordinating conjunction. There are, however, instances when “so” may introduce purpose and in this case “so” is used as a subordinating conjunction.


  • “I took my umbrella with me so I wouldn’t get wet.”
  • ” I stayed so I could see you.”

  1. We use the past simple for past events or actions which have no connection to the present.
  2. We use the present perfect for actions which started in the past and are still happening now OR for finished actions which have a connection to the present.
  3. We CAN’T use the present perfect with a finished time word:
    • NOT: I’ve been to the museum yesterday.

Transportation Prepositions In English: BY, IN, And ON

Prepositions are tricky in all languages because they usually don’t have any rules that a student can memorise and use every time without exception.

Why, for example, do we say we are fond of but in love with someone? Why are we happy about something, but delighted with the same thing? It can certainly be very frustrating for a student when there doesn’t seem to be any logic or consistency to the new language.

When we talk about ways to travel, however, there are a few rules that work 100% of the time. Let’s take a look at them:


General Ways to Travel


When talking about general ways to travel, we always use the preposition “by.” We can travel by bike, by motorcycle, by car, by van, by lorry, by truck, by train, by plane, by bus, by ship, by tram, or by boat.

We can also use by to refer to the transportation environment (by sea, by land, by air) or the surface area (by rail, by road, by water).

Verb Tense Consistency

There are three main verb forms for showing time or tense:

Simple Tense

  • does not use auxiliary verbs
  • refers to specific time period during which

    something happens
    something happened and is over
    something will happen

Simple present (action goes on now):  I sit

Simple past:  (action happened and is over):   I sat

Simple future  (action will happen):   I will sit



 Perfect Tense

  • uses have, has, or had as auxiliary verb
  • allows action to continue over time

Present perfect (action happened and may still be going on):   I have sat

Past perfect (action happened before something happened in the past):  I had sat

Future perfect (action will be considered in the future, by which time it will have already happened):                                                                                                                                      I will have sat


Progressive Tense

  • uses is, are, was, or were as auxiliary verb with –ing ending on main verb
  • focuses on “progress” of action

Present progressive (action is in progress right now):   I am sitting

Past: progressive (action was in progress in the past):  I was sitting

Future progressive (action will be in progress in the future):  I will be sitting


Each of the above tenses denotes a specific time for an action or event to take place.  Writers should be careful to use the exact tense needed to describe, narrate, or explain.

In general . . .

  • Do not switch from one tense to another unless the timing of an action demands that you do.
  • Keep verb  tense consistent in sentences, paragraphs, and essays.


Verb tense consistency on the sentence level

  • Keep tenses consistent within sentences.
  • Do not change tenses when there is no time change for the action.





Since there is no indication that the actions happened apart from one another., there is no reason to shift the tense of the second verb.


Note another example.







The above sentence means that Mary walks into a room at times.  The action is habitual present.  The second action happens when the first one does.  Therefore, the second verb should be present as well.


Change tense only when there is a need to do so.
Usually, the timing of actions within a sentence will dictate when the tense must change.



The first action will take place in the future; therefore, the second one will as well.




The second action took place in the past; the first action occurred before the past action.  Therefore, the first action requires the past perfect tense (had + verb).


Verb tense consistency on the paragraph level

  • Generally, establish a primary tense and keep tenses consistent from sentence to sentence.
  • Do not shift tenses between sentences unless there is a time change that must be shown.



All actions in the above paragraph happen in the present except for the future possibility dependent upon a
present action taking place: ” If a cat sees the bird, the cat will kill it.”



All of the actions in the above paragraph happen in the past except for the possibility dependent upon
one action taking place:  “If a cat saw the bird, the cat would kill it.”


Verb tense consistency on the essay level 

  1. Use present tense when writing essays about
  • your own ideas
  • factual topics
  • the action in a specific movie, play, or book









NOTE:  When quoting from a work, maintain the present tense in your own writing, while keeping the original tense of the quoted material.

EXAMPLE (quoted material is shown in  blue)



  1. Use past tense when writing about
  • past events
  • completed studies or findings,  arguments presented in scientific literature




Note the justified use of present tense in the last sentence (shown in blue).




  1. Use future tense when writing about
  • an event that will occur in the future.




  Remember . . .

  • Change tense ONLY when something in the content of your essay demands that you do so for clarity.

Note how the following example incorporates  tense change as needed to clarify several time periods.
