Future Perfect Tense
The Future Perfect Tense, which is used in situations or events that are expected to end in the future, is one of the most important tense that should be learned by those who want to learn English. When using this Tense, first the subject, then the verb, then the object should be used. For Future Perfect Tense, Future Tense suffix “will”, Perfect Tense suffix “have” and verb conjugated to the third form is used.
How to Use Future Perfect Tense?
For actions completed before an event, action, or situation that will occur in the future, Future Perfect Tense can also express that an action will occur before a future situation. Adverbs of “by”, “by the time” and “when” can be encountered in Future Perfect Tense sentences. The adverb “by the time” must be used with a sentence, while the adverb “by” can be used with any word that indicates time.
Example of a sentence using the adverb “By the time”: By the time my husband arrives home, I am going to have prepared my surprise for my husband.
Example of a sentence using the adverb “By”: By next year, I will have graduated.
The Future Perfect Tense can also be used before a future action. When this Tense is used with static verbs, it is told that an action in the future will continue until another action will take place in the future.
Example of a sentence suitable for an explanation: I will have studied in this university by the time I graduate.
While making a sentence with Future Perfect Tense, the sentence in which Future Perfect Tense is used should not be used after time expressions such as “when, while, before, after, by the time, as soon as, if, unless”, it would be a very big grammatical error.
