Ας μην το αφήσουμε για αύριο· ας στείλουμε σήμερα το email και ας ηρεμήσουμε.

ας is the particle that makes a let’s ... construction in Greek.

So:

• Ας μην το αφήσουμε = Let’s not leave it
• ας στείλουμε = let’s send
• ας ηρεμήσουμε = let’s relax / let’s calm down

More literally, ας introduces a kind of hortatory subjunctive: a suggestion or encouragement involving we.

Yes, Greek often repeats ας before each verb, especially when the sentence has several coordinated actions.

Here it gives a clear rhythm:

• ας μην το αφήσουμε
• ας στείλουμε
• ας ηρεμήσουμε

This sounds very natural. Repeating ας helps mark each verb as part of the same let’s ... sequence.

In some contexts, Greek can avoid repeating it, but in a sentence like this, repetition is common and idiomatic.

Because ας is followed by a subjunctive-type verb form, and Greek normally negates that with μη(ν), not δεν.

A very useful rule is:

• δεν = negates indicative statements
• μη(ν) = negates subjunctive forms, imperatives, and similar constructions

So:

• Δεν το αφήνουμε = We are not leaving it / We don’t leave it
• Ας μην το αφήσουμε = Let’s not leave it

The second one is the correct pattern here.

They are first person plural aorist subjunctive forms.

Specifically:

• αφήσουμε from αφήνω = leave
• στείλουμε from στέλνω = send
• ηρεμήσουμε from ηρεμώ = calm down / relax

After ας, Greek commonly uses the subjunctive. In this sentence, the verbs are in the aorist form, which here does not mean past time. It mainly shows the actions as single, complete actions:

• leave it
• send it
• calm down

So although English uses let’s, Greek grammar is using ας + aorist subjunctive.

Because the speaker is talking about complete actions, not ongoing processes.

Compare the idea:

• ας στείλουμε = let’s send it once, as a complete action
• a present-type form would suggest something more ongoing, repeated, or process-oriented

In this sentence, each action is viewed as a whole:

1. don’t postpone it
2. send the email today
3. then relax

So the aorist subjunctive is exactly what Greek normally uses here.

το means it.

So:

• Ας μην το αφήσουμε για αύριο = Let’s not leave it for tomorrow

This is a clitic object pronoun, and in Greek these unstressed object pronouns usually come before the verb.

A native English speaker may expect leave it, with it after the verb, but Greek normally puts it before:

• το αφήσουμε = leave it

Here, το probably refers to the task or matter under discussion, and the next clause makes it clear that the concrete action is sending the email.

Yes, literally για αύριο means for tomorrow, but in this context it means:

• until tomorrow
• to tomorrow
• for tomorrow, in the sense of postponing it

So Ας μην το αφήσουμε για αύριο is a very natural Greek way to say:

• Let’s not leave it for tomorrow
• Let’s not put it off until tomorrow

This is an idiomatic and common use of για with time expressions.

Because email is commonly treated as a neuter loanword in Greek, especially in everyday usage.

So:

• το email

That is very common in Modern Greek.

You may also see more fully Greek alternatives such as:

• το ηλεκτρονικό μήνυμα
• το μέιλ in more informal spelling/usage

But το email is extremely normal in contemporary Greek.

Greek word order is more flexible than English word order.
Here:

• ας στείλουμε σήμερα το email

puts σήμερα in a natural position after the verb.

It can help emphasize today a little:

• let’s send the email today

Greek could also say:

• ας στείλουμε το email σήμερα

That would also be correct. The difference is mostly one of emphasis, flow, and style rather than basic meaning.

Literally, ηρεμήσουμε means let’s calm down or let’s become calm.

In context, it often has the broader sense:

• let’s relax
• let’s stop worrying
• let’s get it over with and feel relieved

So the idea of the whole sentence is something like:

• don’t postpone it
• send the email today
• then we can relax

It is not just about physical calmness; it often suggests mental relief too.

The mark · is called the άνω τελεία in Greek.

In modern texts, it often works like an English:

• semicolon
• or sometimes a strong colon-like pause

So in this sentence:

• Ας μην το αφήσουμε για αύριο· ας στείλουμε σήμερα το email και ας ηρεμήσουμε.

it separates two closely connected thoughts:

1. Let’s not leave it for tomorrow
2. Let’s send the email today and relax

Important: this is not the Greek question mark.
The Greek question mark looks like:

• ;

So learners should not confuse:

• · = ano teleia
• ; = question mark in Greek

It is fairly neutral everyday Greek.

A few points:

• ας makes it sound like a suggestion: cooperative, natural, conversational
• το email is modern and everyday
• the sentence could easily be said between coworkers, friends, or family members

So it is neither very slangy nor especially formal. It sounds like normal spoken or written Modern Greek.

Not in the same way, because the speaker is including themself in the action.

English uses let’s, and Greek uses ας + subjunctive for that idea.

Imperatives are used for commands like send!, but not naturally for let’s send. Since the meaning here is we should do this, Greek needs the ας construction.

So this is the standard way to express:

• Let’s not leave it for tomorrow; let’s send the email today and relax.
