Gençler, bağımsız kararlar verebilmek için sürekli çaba harcar.

Probably not. In this sentence, Gençler means young people / the youth as the subject, not Hey, young people!

That comma is most likely just a stylistic pause or topic-marking comma. In standard plain writing, you could usually write:

Gençler bağımsız kararlar verebilmek için sürekli çaba harcar.

So yes, a native English speaker might read the comma as direct address, but here it is better understood as a pause, not a vocative.

This is a very common Turkish feature.

With a clear plural subject like gençler, Turkish can use either:

• harcar
• harcarlar

Both can be correct, depending on style and emphasis.

Why is singular possible?

• In general statements about a group, Turkish often uses the 3rd person singular verb form
• The plural meaning is already clear from gençler

So this sentence means something like a general truth about young people, and harcar sounds natural.

Harcar is the aorist / simple present form of harcamak.

Here it expresses:

• a habitual action
• a general tendency
• something that is usually true

So it is not necessarily right now they are making an effort, but rather:

• young people generally make an effort
• young people tend to make an effort

If you wanted are making an effort right now, you would normally use a present continuous form like harcıyorlar.

Çaba means effort.

Harcamak literally means to spend. So çaba harcamak literally means to spend effort, but in natural English it means:

• to make an effort
• to put in effort
• to strive

It is a very common Turkish expression.

So:

• çaba = effort
• çaba harcamak = to make an effort

Yes, you can say çabalar because çabalamak means to strive / to make an effort.

So these are close:

• sürekli çaba harcar
• sürekli çabalar

But çaba harcamak is often a little more idiomatic in contexts like this, where the idea is putting in sustained effort.

Verebilmek can be broken down like this:

• ver- = give
• -e bil- = can / be able to
• -mek = infinitive ending

So:

• vermek = to give
• verebilmek = to be able to give

In this sentence, because of the noun kararlar, the expression means to be able to make decisions, even though vermek literally means to give.

Yes, literally it does.

In Turkish, karar vermek is the normal expression for:

• to decide
• to make a decision

So even though the literal parts are decision + give, you should learn karar vermek as a fixed expression.

In this sentence, kararlar verebilmek means:

• to be able to make decisions
• more specifically, to be able to make independent decisions

Because the sentence is talking about decisions in general, not one single decision.

• karar vermek = to make a decision
• kararlar vermek = to make decisions

Using the plural here suggests an ongoing ability across many situations, which fits the general meaning of the sentence.

İçin means for or in order to, depending on context.

Here it marks purpose:

• bağımsız kararlar verebilmek için = in order to be able to make independent decisions

A very useful pattern is:

• verb + -mek/-mak için = in order to ...
• verb + -(y)ebilmek + için = in order to be able to ...

So this sentence uses:

• verebilmek için = in order to be able to make/give

Because Turkish normally places adjectives before the noun, just like English often does.

So:

• bağımsız = independent
• kararlar = decisions
• bağımsız kararlar = independent decisions

If you said kararlar bağımsız, that would usually mean the decisions are independent, which is a different structure.

Bağımsız means independent.

In this sentence, it describes decisions made without too much outside control or dependence. So bağımsız kararlar suggests:

• decisions made on one’s own
• self-directed decisions
• autonomous decisions

Sürekli means:

• constantly
• continually
• consistently

It functions as an adverb here and modifies the whole action çaba harcar.

Turkish word order is flexible, but this placement is very natural:

bağımsız kararlar verebilmek için sürekli çaba harcar

It emphasizes that the effort is ongoing or repeated.

Yes. Turkish allows quite a lot of word order flexibility, especially for emphasis.

The neutral order here is very natural:

• Gençler bağımsız kararlar verebilmek için sürekli çaba harcar.

But you could move pieces around for emphasis, for example:

• Gençler sürekli bağımsız kararlar verebilmek için çaba harcar.
• Bağımsız kararlar verebilmek için gençler sürekli çaba harcar.

The basic meaning stays similar, but the focus changes slightly.

Because Turkish is typically an SOV language:

• Subject
• Object / complements
• Verb

Here:

• Gençler = subject
• bağımsız kararlar verebilmek için sürekli çaba = the rest of the information
• harcar = verb at the end

English speakers often need time to get used to this, because English usually puts the main verb much earlier.

Here it most naturally means young people in general or the youth as a group.

A bare plural noun in Turkish often has this generic meaning. So gençler here is not necessarily a specific set of young people that both speakers already know; it can be a general category.

Yes:

Gençler, bağımsız kararlar verebilmek için sürekli çaba harcarlar.

This is also understandable and acceptable.

The version with harcar sounds slightly more like a general statement about a group, while harcarlar can sound a bit more explicitly tied to the plural subject. In practice, both are possible.
