Bu kış kayak yapacağım.

Bu kış means this winter.

• bu = this
• kış = winter

Together, they form a time expression. In Turkish, time expressions often come near the beginning of the sentence:

• Bu kış kayak yapacağım. = I will ski this winter.

Turkish often expresses some activities with a noun + yapmak structure.

Here:

• kayak = skiing / ski
• yapmak = to do / to make

So kayak yapmak literally means to do skiing, but in natural English it means to ski.

This is very common in Turkish:

• spor yapmak = to do sports / exercise
• kahvaltı yapmak = to have breakfast
• alışveriş yapmak = to do shopping

So kayak yapacağım is the normal way to say I will ski.

Yapacağım comes from the verb yapmak (to do / to make).

It breaks down like this:

• yap- = verb stem
• -acak / -ecek = future tense suffix
• -ım / -im / -um / -üm = I ending

Because of vowel harmony and sound changes, yap- becomes:

• yap + acak + ım
• → yapacağım

So yapacağım means I will do.

In this sentence, since it follows kayak, it means I will do skiing → I will ski.

This happens because Turkish adds personal endings after the future tense suffix.

The underlying pieces are:

• yap-
• -acak (future)
• -ım (I)

When these combine, Turkish changes the form for smoother pronunciation:

• yapacakım is not the actual final form
• it becomes yapacağım

A useful pattern to recognize is:

• geleceğim = I will come
• yapacağım = I will do
• bakacağım = I will look

So when you see -acağım / -eceğim, it often means I will ...

Turkish often drops the subject pronoun when the verb already shows who is doing the action.

• yapacağım already means I will do
• so ben (I) is not necessary

You could say:

• Ben bu kış kayak yapacağım.

But usually ben is omitted unless you want emphasis, contrast, or clarity.

For example:

• Ben bu kış kayak yapacağım, o ise yüzecek. = I will ski this winter, but he/she will swim.

The sentence follows a very common Turkish pattern:

time expression + object/activity + verb

So:

• Bu kış = time
• kayak = activity noun
• yapacağım = verb

Turkish usually puts the main verb at the end.

That said, Turkish word order is flexible for emphasis. For example:

• Kayak yapacağım bu kış. still means roughly I will ski this winter, but it sounds more marked or emphatic.

The most neutral version is:

• Bu kış kayak yapacağım.

A rough pronunciation guide:

• Bu ≈ boo
• kış ≈ kush but with a short, neutral vowel; ı is not the English i
• kayak ≈ ka-yak
• yapacağım ≈ ya-pa-ja-um or ya-pa-dja-um, depending on accent and speed

A few key sounds:

• ş = sh
• c = j as in jam
• ğ usually does not sound like a strong consonant; it often lengthens or smooths the previous vowel
• ı is a special Turkish vowel, not the same as English i

So:

• kış has ı, not i
• yapacağım contains ğ, which is soft

The letter ı is one of the sounds English speakers often find tricky.

It is:

• not like English ee
• not like English ih
• a deeper, more central vowel made without rounding your lips

In kış, try saying something like kush, but without a full English u sound. It is closer to a neutral vowel.

Compare:

• kış = winter
• kişi = person

Those two words have different vowels, and that difference matters in Turkish.

By itself, -acak / -ecek usually expresses the future: will / going to, depending on context.

So Bu kış kayak yapacağım can mean:

• I will ski this winter
• I’m going to ski this winter

It often suggests an intention or plan, but not necessarily a firm appointment.

Context decides how strong it sounds:

• casual intention
• expectation
• plan

If you want to sound more like a firm plan in context, Turkish may add words such as:

• kesinlikle = definitely
• sanırım = I think
• galiba = probably

Yes. In natural English, I will ski this winter and I will go skiing this winter are both good translations, depending on context.

Turkish uses kayak yapmak, which focuses on the activity itself. English may translate it in slightly different natural ways:

• I will ski this winter.
• I’m going skiing this winter.
• I will go skiing this winter.

All of these can fit, depending on the situation.

Usually, no, if you mean I will ski as an activity.

The common expression is:

• kayak yapmak = to ski

The verb kaymak more basically means to slide / slip / glide.

So:

• Kayacağım would normally mean something like I will slide / slip not the standard way to say I will ski.

That is why kayak yapacağım is the natural choice.

You keep kayak yap- and change the verb ending.

Examples:

• Bu kış kayak yapacağım. = I will ski this winter.
• Bu kış kayak yapacaksın. = You will ski this winter.
• Bu kış kayak yapacak. = He/She will ski this winter.
• Bu kış kayak yapacağız. = We will ski this winter.
• Bu kış kayak yapacaksınız. = You (plural/formal) will ski this winter.
• Bu kış kayak yapacaklar. = They will ski this winter.

This is a very useful pattern to learn.

You can, but it usually means something a bit different.

• Bu kış kayak yapacağım = I will ski this winter
• Bu kış kayak yapıyorum literally uses the present continuous, but Turkish often uses it for planned future actions too

So yapıyorum can sometimes mean:

• I am skiing this winter
• I’m going skiing this winter
• I’m skiing this winter as a planned arrangement

However, yapacağım is the clearer and more straightforward future form if you simply want to say I will ski this winter.

Yes. Turkish suffixes change shape to match the vowels in the word.

In this sentence:

• kış contains the vowel ı
• yapacağım contains endings shaped by vowel harmony

For the future tense, the suffix appears as:

• -acak or
• -ecek

Here it is -acak:

• yapacak...

Then the I ending also changes according to vowel harmony:

• -ım / -im / -um / -üm

In the final form, this becomes:

• yapacağım

You do not need to calculate every detail perfectly at first, but it helps to recognize that Turkish endings often come in matching vowel forms.
