Öyleyse hemen başlayalım.

Öyleyse means something like then, so, or in that case.

It is made from:

• öyle = like that / so
• ise = a form that can mean if it is / as for / then

Together, öyleyse works as a connector between ideas:

• If that’s so, then...
• In that case...
• So then...

In natural English, Öyleyse hemen başlayalım. is often rendered as Then let’s start right away or So, let’s begin immediately.

Yes. Öyleyse is essentially the fused form of öyle ise.

You may see:

• öyle ise
• öyleyse

In modern everyday Turkish, öyleyse is very common and natural.

So:

• öyle ise = if that is so / in that case
• öyleyse = the same meaning, just written as a single, fixed expression

Hemen means immediately, right away, or at once.

In this sentence, it comes before the verb phrase:

• Öyleyse hemen başlayalım.

That placement is very natural in Turkish. It modifies the action of starting, so it tells you when/how quickly the action should happen.

You can think of it as:

• Then let’s start immediately
• Then let’s begin right away

Turkish word order is flexible, but this version sounds smooth and standard.

Başlayalım means let’s start or let’s begin.

It comes from the verb başlamak, meaning to start / to begin.

Breakdown:

• başla- = verb stem from başlamak
• -yalım / -alım = let’s ... form for we

So başlayalım is a first person plural suggestion/command, often called the let’s form.

Examples:

• Gidelim. = Let’s go.
• Yiyelim. = Let’s eat.
• Başlayalım. = Let’s start.

Because the sentence is making a suggestion or proposal, not stating an ongoing action.

Compare:

• başlayalım = let’s start
• başlıyoruz / başlıyoruz = we are starting
• başlayacağız = we will start

So:

• Öyleyse hemen başlayalım. = Then let’s start right away.
• Öyleyse hemen başlıyoruz. would mean Then we are starting right away, which is more of a statement than a suggestion.

The -alım / -elim ending is used when the speaker includes themself and says let’s do X.

This is because of how Turkish connects sounds smoothly.

The verb stem here is effectively başla-. When the let’s ending is added, Turkish inserts a y to make pronunciation easier:

• başla + alım → başlayalım

That y is a common buffer consonant in Turkish.

You will see the same kind of thing in many words and forms when two vowels would otherwise come together.

So the important thing to remember is:

• başlayalım = correct natural form
• the y helps link the vowels smoothly

Yes. Turkish often leaves out subject pronouns when the verb ending already shows the subject.

In başlayalım, the ending already tells you it means let us / we should.

So:

• (Biz) başlayalım. = Let’s start.

Including biz is possible, but usually unnecessary unless you want extra emphasis.

For example:

• Biz başlayalım. = Let’s be the ones to start / We should start.

Without biz, the sentence sounds more neutral and natural in most situations.

Başlamak is usually intransitive when it means to begin / to start.

So:

• Başlayalım. = Let’s begin.

No object is required.

If you want to say start something, Turkish often uses başlatmak, which is causative:

• Dersi başlatalım. = Let’s start the lesson.

But başlamak can also appear with something that is beginning:

• Ders başladı. = The lesson started.

In your sentence, başlayalım simply means let’s begin without naming exactly what is being begun.

It is neutral and widely usable. It is not rude, and it is not especially formal either.

You could use it in many contexts:

• a teacher starting a lesson
• a presenter beginning a talk
• friends beginning an activity
• an online course introducing a topic

Because başlayalım includes the speaker and the listener(s), it sounds friendly and cooperative: let’s start rather than a direct command like start!

Yes, Turkish allows some flexibility, but Öyleyse hemen başlayalım is a very natural default order.

Current order:

• Öyleyse = sets up the transition: then / in that case
• hemen = adds urgency: right away
• başlayalım = main action: let’s start

Possible alternatives can exist, but they may shift emphasis:

• Hemen başlayalım, öyleyse.
• Başlayalım öyleyse.

These are understandable, but Öyleyse hemen başlayalım. sounds especially smooth as a standard spoken or written line.

A rough pronunciation guide:

• Öyleyse ≈ UH-y-leh-y-seh
• hemen ≈ heh-MEN
• başlayalım ≈ bash-lah-YAH-luhm

A few helpful notes:

• ö is like the vowel in German schön or French peu.
• ş sounds like sh.
• ı is the Turkish vowel with no exact English equivalent; it is a dull, central vowel.
• Stress in başlayalım is often felt near -ya-, though Turkish stress patterns can vary.

A smooth full reading is:

Öyleyse hemen başlayalım.

Yes. That is a very natural translation.

Depending on context, öyleyse can be translated in several ways:

• then
• so
• well then
• in that case

And başlayalım can be:

• let’s start
• let’s begin

So all of these can work:

• Then let’s start right away.
• So, let’s begin immediately.
• Well then, let’s get started.
• In that case, let’s begin at once.

The best English version depends on tone and context, not just grammar.
