Let us consider the following sentences first.
A. I might marry Angelina Jolie in 2025.
B. I will marry Angelina Jolie in 2025.
C. I am going to marry Angelina Jolie in 2025.
D. I am marrying Angelina Jolie in 2025.
By looking at our sample sentences above, what did you notice? Did you find any commonalities? Did you find any differences?
Well, one similarity we have there is we can see the time marker “in 2025” in every sentence. In English grammar, we call this one the “definite future time marker.” The definite future time marker tells us that the action will surely happen in the exact/definite time in the future.
On the other hand, the difference we have here is that each sentence uses different modal verbs/ grammatical patterns to express future action. Right? Let us highlight the modal verbs and grammatical patterns we used in each of the sentences.
1. Might + (base form of the verb)
2. Will + (base form of the verb)
3. be verb + going to + (base form of the verb)
4. be verb + verb (-ing form)
P.S. The verb we used in the sentence is the word “marry” which is in its base form. Also, please note that the modal verbs might and will must not be followed with a past form or -s form of the verb.
As you can now see, all these grammatical patterns tell us that the action will happen in the future, which is in 2025. But do they tell you how certain and possible the action will happen? NO.
