The present tense in Greek does double duty as both simple present and continuous present tense. That is, if you say: Αυτός γράφει ένα γράμμα. You may translate it as either “He writes a letter” or “He is writing a letter,” depending on your meaning. There's no distinction between these forms in present tense.

Future Continuous

We're going to look at future tense first. Once you learn future tense, it becomes very easy to construct the past tense of Greek verbs; it just doesn't work as well the other direction. So be patient as we learn the future tense so that, sometime in the future, you'll be able to talk about the past.

Although Greek doesn't make any distinction between “I write” and “I am writing” in present tense, they do make the distinction in the future tense.

There's one form for “I will be writing” and another for “I will write.”

The “will be ...ing” form is called the future continuous, and is used to denote actions that take place over an extended period of time or occur repeatedly.

Here are some English examples:

I will be writing web pages for six hours.
He will be giving his wife flowers every week.
They will be doing exercises every day.

This sounds weird in English; we'd usually just use the simple form of the future, and let the words like “every day” prompt us in to the continuity. I will be using the continuous form in the following example to emphasize that we are working with future continuous.

Future continuous is the easiest tense to form; just add the word θα before the present tense, and there you have it.

The Greek word for future continuous is μέλλοντας εξακολουθητικός.
