Bugünkü gündem kısa, bu yüzden sadece iki slayt göstereceğim.

Bugünkü means today’s or the one for today.

It is built from:

• bugün = today
• -kü = a suffix that turns a time/place expression into something like an adjective

So:

• bugün → today
• bugünkü → today’s / the one for today

In this sentence, bugünkü gündem means today’s agenda.

This suffix is common with time and place words:

• dünkü gazete = yesterday’s newspaper
• yarınki toplantı = tomorrow’s meeting
• evdeki kitap = the book in the house / the book at home

Because of sound and spelling rules, it appears as -ki / -kü / -ki depending on the word.

Both are possible, but they are slightly different in style and structure.

• bugünkü gündem = today’s agenda
• bugünün gündemi = the agenda of today

The first one is often more compact and adjective-like. The second one uses a genitive-possessive structure:

• bugünün = of today
• gündemi = its agenda / the agenda

In many everyday contexts, bugünkü gündem sounds very natural and efficient.

Turkish often leaves out the verb to be in the present tense.

So:

• gündem kısa literally looks like agenda short
• but it means the agenda is short

This is completely normal in Turkish.

Compare:

• Hava güzel. = The weather is nice.
• Toplantı uzun. = The meeting is long.
• Gündem kısa. = The agenda is short.

If you need past or future, Turkish usually adds something:

• Gündem kısaydı. = The agenda was short.
• Gündem kısa olacak. = The agenda will be short.

Gündem usually means agenda, schedule of topics, or sometimes current issues / what is being discussed.

In a meeting or presentation context, gündem is very naturally agenda.

Examples:

• Toplantının gündemi = the agenda of the meeting
• Bugünkü gündem = today’s agenda
• Gündemde ne var? = What is on the agenda?

So in this sentence, it refers to the presentation or meeting agenda.

Bu yüzden means because of this, for this reason, or simply so in this kind of sentence.

Here it connects the two ideas:

• the agenda is short
• therefore only two slides will be shown

Similar expressions:

• bu yüzden = because of this / so
• bu nedenle = for this reason, therefore
  
  • often a bit more formal
• o yüzden = that’s why / so
  
  • very common in spoken Turkish

All three can work in many situations, but:

• bu yüzden = neutral and very common
• o yüzden = especially common in conversation
• bu nedenle = slightly more formal or written

Sadece means only / just, and it usually comes right before the thing it limits.

So:

• sadece iki slayt = only two slides

That means the limitation is on the number of slides.

If you move sadece, the focus can shift slightly. Turkish is flexible, but placement affects emphasis.

For example:

• Sadece iki slayt göstereceğim. = I will show only two slides.
• İki slayt sadece göstereceğim. = unnatural in most contexts
• İki slayt göstereceğim sadece. = possible in speech, more emphatic or conversational

The version in your sentence is the most natural standard order.

After numbers, Turkish nouns normally stay singular.

So:

• bir slayt = one slide
• iki slayt = two slides
• üç slayt = three slides

This is a very important difference from English.

More examples:

• iki kitap = two books
• beş öğrenci = five students
• on dakika = ten minutes

Using the plural after a number is usually incorrect in standard Turkish.

Göstereceğim means I will show.

It can be broken down like this:

• göster- = show
• -ecek / -acak = future tense marker
• -im / -ım / -um / -üm = first person singular, I

So:

• göster-
• göster-ecek
• göstereceğim = I will show

The form changes slightly because of vowel harmony and consonant behavior, but the basic pattern is:

verb stem + future + person

More examples:

• geleceğim = I will come
• anlatacağım = I will explain
• yapacağım = I will do

There is no extra written y in göstereceğim, but learners often notice that the pronunciation seems to flow with a glide.

The important thing is that Turkish attaches endings smoothly, and when suffixes combine, some sounds soften or merge naturally in speech.

The structure is still:

• göster
• -ecek
• -im

Historically and morphologically, the form comes from gösterecek + im, which becomes göstereceğim.

You do not need to insert a separate y here in spelling. Just learn the full future forms as standard patterns:

• göstereceğim = I will show
• göstereceksin = you will show
• gösterecek = he/she/it will show

Turkish often drops subject pronouns because the verb ending already shows who the subject is.

In göstereceğim, the ending tells you the subject is I.

So:

• göstereceğim = I will show
• ben göstereceğim = I will show

Both are possible, but ben is usually omitted unless you want emphasis or contrast.

For example:

• Ben göstereceğim, Ayşe değil. = I will show them, not Ayşe.
• Sadece iki slayt göstereceğim. = I will show only two slides.

This pronoun-dropping is very normal in Turkish.

Not completely. Turkish word order is flexible, but some orders sound more neutral than others.

The sentence:

• Bugünkü gündem kısa, bu yüzden sadece iki slayt göstereceğim.

is very natural and neutral.

The most neutral place for the verb is often near the end, which is what we see here.

You could rearrange parts for emphasis, for example:

• Bugünkü gündem kısa, bu yüzden iki slayt göstereceğim sadece.
• Bu yüzden sadece iki slayt göstereceğim; bugünkü gündem kısa.

These are possible, but the original version is clearer and more standard.

For learners, the safest pattern is:

• topic/reason first
• details next
• verb at the end

The comma links two closely connected statements:

• Bugünkü gündem kısa
• bu yüzden sadece iki slayt göstereceğim

This works well because the second part is a direct result of the first.

You could also write them as two sentences:

• Bugünkü gündem kısa. Bu yüzden sadece iki slayt göstereceğim.

That would also be correct.

So the comma here is mainly a punctuation choice showing a smooth connection between cause and result.

Slayt is a loanword, based on English slide, and it is very commonly used in Turkish for presentation slides.

So yes, it sounds natural.

Examples:

• Bir slayt hazırla. = Prepare a slide.
• Sunumda kaç slayt var? = How many slides are in the presentation?
• İlk slaytı göster. = Show the first slide.

In business, school, and presentation contexts, slayt is completely normal Turkish usage.
