İkinci el kıyafetler askılığa asıldı.

Yes. Literally, ikinci el is second hand, just like in English. As a fixed expression in Turkish, it means used / second-hand.

• ikinci = second
• el = hand

Together:

• ikinci el kıyafetler = second-hand clothes

In Turkish, this is a very common compound phrase:

• ikinci el araba = second-hand car
• ikinci el telefon = used phone

Because ikinci el functions like an adjective phrase here, and adjectives in Turkish do not agree with the noun in number.

So:

• ikinci el kıyafet = a second-hand piece of clothing / second-hand clothing
• ikinci el kıyafetler = second-hand clothes

Only the noun takes the plural ending:

• kıyafet = clothing item / outfit / garment
• kıyafetler = clothes

This is normal in Turkish:

• güzel ev = beautiful house
• güzel evler = beautiful houses

Notice güzel stays the same.

-ler / -lar is the regular Turkish plural suffix.

Here:

• kıyafet = clothing item, outfit, garment
• kıyafetler = clothes / garments

Why -ler and not -lar? Because of vowel harmony. The last vowel in kıyafet is e, so the plural becomes -ler.

Compare:

• ev → evler
• kitap → kitaplar

Askılığa means to the hanger / onto the clothes hanger / onto the rack, depending on context.

It comes from:

• askı = hanger, something used for hanging
• askılık = hanger, coat rack, hanging stand, clothes rack
• askılığa = to/onto the hanger or rack

The ending -a / -e is the dative case, often meaning:

• to
• toward
• onto

So askılığa asıldı means something like:

• was hung on the rack
• was hung onto the hanger

The exact English wording depends on the situation.

Because of a common Turkish sound change called consonant softening.

The dictionary form is:

• askılık

When a vowel-initial ending is added, the final k often changes:

• k → ğ

So:

• askılık
  • -a → askılığa

You see the same pattern in many words:

• çocuk → çocuğa
• renk → renge
• yemek → yemeğe

This is very normal in Turkish.

Asıldı is the past tense of the verb asılmak here, meaning to be hung or to get hung up.

The base idea is:

• asmak = to hang something
• asılmak = to be hung / to hang oneself / to cling, depending on context

In this sentence, it is the passive/intransitive-type meaning:

• kıyafetler askılığa asıldı = the clothes were hung on the rack

Breakdown:

• asıl- = be hung / get hung
• -dı / -di / -du / -dü = past tense

So:

• asıldı = was hung / got hung

For a learner, it is useful to think of it that way, yes.

Compare:

• Birisi kıyafetleri askılığa astı. = Someone hung the clothes on the rack.
• Kıyafetler askılığa asıldı. = The clothes were hung on the rack.

In the second sentence, the doer is not mentioned, and the focus is on what happened to the clothes. That is why English often translates it with a passive:

• were hung

So even though Turkish grammar can describe this in slightly different ways depending on the verb analysis, passive-like is the practical understanding here.

Turkish word order is flexible, but the most neutral order is often:

subject + other elements + verb

So here:

• İkinci el kıyafetler = subject
• askılığa = destination/location-like phrase
• asıldı = verb

That gives:

• İkinci el kıyafetler askılığa asıldı.

Other orders are possible for emphasis:

• Askılığa ikinci el kıyafetler asıldı.
• Asıldı ikinci el kıyafetler askılığa. (much less neutral, very marked)

The most natural unmarked version is the original sentence, with the verb at the end.

Turkish does not have a definite article like English the.

So:

• kıyafetler can mean clothes or the clothes
• the exact meaning depends on context

Likewise:

• askılığa can mean to a hanger/rack or to the hanger/rack

Turkish often leaves definiteness to context rather than marking it with a separate word.

Because kıyafetler is the subject here, not the direct object.

Compare:

1. İkinci el kıyafetler askılığa asıldı.

   • kıyafetler = subject
   • no accusative

2. Birisi ikinci el kıyafetleri askılığa astı.

   • kıyafetleri = direct object
   • here it takes the accusative -i

So:

• kıyafetler = the clothes / clothes, as subject
• kıyafetleri = the clothes, as definite object

Yes. Askılık can refer to several related things depending on context:

• a hanger
• a coat rack
• a clothes rack
• a place for hanging things

So askılığa asıldı could suggest:

• hung on a hanger
• hung on a clothes rack
• placed on a hanging stand

The exact image depends on the situation. Turkish often uses one practical word where English may choose among several more specific ones.

A rough pronunciation guide:

İkinci el kıyafetler askılığa asıldı
ee-KEEN-jee el kuh-yah-FET-ler ah-skuh-LUH-ah ah-suhl-DUH

A few helpful notes:

• ı is not English i. It is a deeper, unrounded vowel, something like a relaxed vowel in sofa, but further back.
• ğ in askılığa usually does not sound like a strong consonant. It mostly lengthens or smooths the vowel before it.
• Stress in Turkish often falls near the end, but compounds and suffixes can affect this.

A more careful syllable breakdown:

• İ-kin-ci
• el
• kı-ya-fet-ler
• as-kı-lı-ğa
• a-sıl-dı

Yes. This is something English speakers often notice.

In Turkish:

• kıyafet is grammatically singular
• but it can refer to an outfit, a garment, or clothing in a general sense

Then:

• kıyafetler clearly means multiple clothing items: clothes, garments

So in this sentence, the plural makes it clear that multiple items were hung up:

• İkinci el kıyafetler = second-hand clothes

A useful beginner breakdown is:

• İkinci el = second-hand
• kıyafetler = clothes
• askılığa = onto/to the hanger or rack
• asıldı = were hung

So the structure is:

[second-hand] [clothes] [onto the hanger/rack] [were hung]

That helps you see the grammar clearly:

• adjective phrase
• subject noun
• dative phrase
• past passive-like verb
