Tenses Questions
The future perfect continuous tense is used to describe an ongoing action that will be happening in the future and will continue until a specific point in time. It is formed by using "will have been" + present participle (-ing form of the verb).
Example: By next year, I will have been studying English for 10 years.
On the other hand, the present continuous tense is used to describe an ongoing action that is happening at the present moment. It is formed by using the present tense of "to be" (am, is, are) + present participle (-ing form of the verb).
Example: I am studying English right now.
In summary, the main difference between the future perfect continuous and present continuous tenses is that the future perfect continuous tense refers to an ongoing action in the future, while the present continuous tense refers to an ongoing action in the present.
