Şayet geçerlilik süresi dolarsa yenileme eğitimini hemen planlayacağız.

Şayet means if.

It is correct and natural, but it sounds a bit more formal or written than eğer. In everyday speech, many speakers would more often say:

• Eğer geçerlilik süresi dolarsa...
• or simply Geçerlilik süresi dolarsa...

So şayet is not wrong at all; it just has a slightly more formal tone.

Yes, both mark a condition.

In this sentence:

• şayet = if
• dolarsa = if it expires

The suffix -sa / -se is the real grammatical conditional marker. Words like şayet or eğer are optional extra signals that introduce the condition more clearly.

So:

• Şayet geçerlilik süresi dolarsa...
• Eğer geçerlilik süresi dolarsa...
• Geçerlilik süresi dolarsa...

are all possible. The last one is often the most straightforward and common.

This is a Turkish noun compound.

• geçerlilik = validity
• süre = duration / period
• süresi = its period / period of

So geçerlilik süresi means validity period or period of validity.

This is a very common Turkish pattern:

• first noun stays bare
• second noun takes the compound ending, which looks like a 3rd person possessive ending

Other examples:

• ders kitabı = textbook
• kimlik kartı = identity card
• geçerlilik süresi = validity period

So even though it may look strange from an English perspective, this is standard Turkish noun-compound structure.

Geçerlilik is formed from:

• geçerli = valid
• -lik = a suffix that turns an adjective or noun into an abstract noun

So:

• geçerli = valid
• geçerlilik = validity

This -lik / -lık / -luk / -lük suffix is very common in Turkish.

For example:

• temiz = clean → temizlik = cleanliness / cleaning
• rahat = comfortable → rahatlık = comfort
• geçerli = valid → geçerlilik = validity

Dolarsa comes from the verb dolmak.

Basic meanings of dolmak include:

• to become full
• to fill up
• in time-related expressions, to run out / expire

In this sentence, it is used in the expression:

• süresi dolmak = for its period to end / to expire

So dolarsa means if it expires or if its validity runs out.

A useful breakdown is:

• dolar = it expires / it becomes full
• -sa = if

So:

• dolarsa = if it expires

That is a very common learner question.

Yes, dolmak often literally means to fill up. But in Turkish, it is also used idiomatically with time-related nouns:

• süre doldu = the time ran out
• vize süresi doldu = the visa period expired
• geçerlilik süresi doldu = the validity period expired

So this is a fixed and very common expression:

• süresi dolmak = to expire

It may feel unusual if you translate word-for-word, but it is completely natural Turkish.

Because it is the direct object of the verb planlayacağız, and it is a specific, definite thing.

The base phrase is:

• yenileme eğitimi = renewal training / refresher training

When that whole phrase becomes a definite direct object, Turkish adds the accusative ending. Because the noun already has the compound ending -i, the accusative appears as -ni after it:

• yenileme eğitimi = the renewal training
• yenileme eğitimini = the renewal training, as a direct object

So in:

• yenileme eğitimini planlayacağız the meaning is we will plan the renewal training.

Yenileme comes from the verb yenilemek, which means to renew.

So:

• yenilemek = to renew
• yenileme = renewal / renewing

In yenileme eğitimi, it functions as the first part of a noun compound:

• yenileme eğitimi = renewal training / refresher training

Depending on context, English might translate this as:

• renewal training
• refresher training
• recertification training

Because Turkish usually puts the subject information inside the verb ending.

In planlayacağız:

• planla- = plan
• -yacak / -yecek = future
• personal ending = we

So planlayacağız means we will plan.

Turkish often leaves out subject pronouns like biz unless they are needed for emphasis.

So:

• yenileme eğitimini hemen planlayacağız = we will plan the renewal training immediately
• biz yenileme eğitimini hemen planlayacağız = we will plan it, with extra emphasis on we

It is built from the verb planlamak = to plan.

The form breaks down like this:

• planla- = verb stem
• -yacak / -yecek = future tense marker
• -ız / -iz / -uz / -üz = 1st person plural ending, depending on vowel harmony

So the underlying structure is roughly:

• planla + yacak + ız

which becomes:

• planlayacağız = we will plan

Two things to notice:

1. A buffer y appears because the stem ends in a vowel.
2. The k in the future marker becomes ğ before the following vowel in the personal ending.

That is why you get -yacağız, not -yacakız.

Yes, Turkish word order is flexible, but the neutral pattern usually puts the verb at the end.

This sentence is structured as:

• conditional clause first: Şayet geçerlilik süresi dolarsa
• object + adverb + verb: yenileme eğitimini hemen planlayacağız

That is very natural Turkish.

You could also hear variations such as:

• Şayet geçerlilik süresi dolarsa hemen yenileme eğitimini planlayacağız.
• Geçerlilik süresi dolarsa yenileme eğitimini hemen planlayacağız.

These are all possible, but the exact placement can slightly change what is emphasized. The version you were given sounds neutral and natural.

Yes, absolutely.

A very natural version is:

• Geçerlilik süresi dolarsa yenileme eğitimini hemen planlayacağız.

This already means If the validity period expires, we will plan the renewal training immediately.

Because dolarsa already contains the conditional meaning if it expires, şayet is optional. Adding şayet just makes the conditional relationship more explicit, and can sound a little more formal or written.
