Kullanım izine rağmen bol kesimi seçti.

Rağmen means despite / in spite of and it normally follows a noun or noun phrase in the dative case.

So the pattern is:

X-e rağmen = despite X

Examples:

• yağmura rağmen = despite the rain
• uyarıya rağmen = despite the warning

In your sentence, the part before rağmen is the thing being contrasted with the choice.

This is a very good question, because many learners would notice this.

If the intended phrase is kullanım izni meaning permission to use / usage permission, then standard Turkish would normally decline it as:

• kullanım izni
• kullanım iznine rağmen

That is because kullanım izni is a noun compound, and when you add the dative after izni, you get iznine.

So in standard written Turkish, many speakers would expect:

Kullanım iznine rağmen bol kesimi seçti.

The form izine looks unusual here and may be:

• a typo,
• a simplified/non-standard form,
• or something intended by a special context.

So yes: if this is meant to be permission for use, iznine is the form most learners should remember.

Kullanım is a noun meaning use / usage. It is derived from the verb kullanmak meaning to use.

So:

• kullanmak = to use
• kullanım = use, usage

This is very common in Turkish: a verb can produce a related noun.

Other similar patterns:

• üretmek = to produce → üretim = production
• tüketmek = to consume → tüketim = consumption

So kullanım izni literally has the structure use permission.

Bol kesim is a common clothing/fashion expression meaning loose cut or loose fit.

Here:

• bol = loose, roomy
• kesim = cut, style, fit

Together:

• bol kesim = a loose-fitting cut/style

In bol kesimi, the noun kesim has an ending, while bol stays unchanged because it is just modifying the noun.

This is normal in Turkish:

• adjective first
• noun second
• only the noun gets the case ending

Because it is the direct object of the verb seçti and it is being treated as specific/definite.

Turkish often marks a specific direct object with the accusative ending.

So:

• bol kesim seçti = chose a loose cut / chose loose fit in a non-specific sense
• bol kesimi seçti = chose the loose cut / chose that loose-fit option

In this sentence, the speaker is referring to a particular option, so kesim becomes kesimi.

Seçti breaks down like this:

• seç- = choose
• -ti = past tense

So seçti means he/she/it chose.

In the third person singular, Turkish often has no extra personal ending after the past tense. So the form is quite short.

Compare:

• seçtim = I chose
• seçtin = you chose
• seçti = he/she/it chose
• seçtik = we chose

The Turkish past tense is often shown as -DI, but that capital D stands for several possible real forms:

• -dı
• -di
• -du
• -dü
• -tı
• -ti
• -tu
• -tü

The exact form depends on:

1. vowel harmony
2. whether the previous sound is voiced or voiceless

Since seç- ends in ç, which is a voiceless consonant, the suffix uses t instead of d.

So:

• seç + di does not happen
• it becomes seçti

Turkish often leaves the subject unstated if it is clear from context.

So this sentence does not explicitly say he, she, or they in English terms. The verb form seçti tells you it is third person singular, so depending on context it could mean:

• he chose
• she chose
• sometimes it chose if the subject is not a person

If Turkish wants to emphasize the subject, it can add it:

• O bol kesimi seçti. = He/She chose the loose cut.

But very often o is omitted.

Yes. The sentence structure is normal for Turkish.

A simple way to see it is:

• Kullanım izine rağmen = despite the permission for use
• bol kesimi = the loose cut / loose-fit option
• seçti = chose

Turkish commonly puts the verb at the end, and it allows quite a bit of flexibility before the verb.

Putting Kullanım izine rağmen at the beginning gives that contrastive idea early: despite that..., he/she chose...

So the order is natural, even though English would organize the sentence differently.

Yes. It is a very common Turkish structure called an indefinite noun compound.

In this pattern:

• the first noun modifies the second noun
• the second noun usually takes a compound marker, often written as -(s)I

So:

• kullanım izni = use permission
• öğrenci kartı = student card
• okul müdürü = school principal
• yaz tatili = summer vacation

When you add a case ending to this kind of phrase, it goes on the second noun:

• öğrenci kartını
• okul müdürüne
• kullanım iznine

That is why learners often expect iznine in your sentence.
