Matkap sanki sıkışmış gibi görünüyor.

Yes:

• matkap = drill
• sanki = as if, seemingly
• sıkışmış = stuck, jammed, having got stuck
• gibi = like, as if
• görünüyor = looks, seems, appears

A very literal structure is:

• Matkap
  • sanki sıkışmış gibi
    • görünüyor
• The drill
  • as if stuck
    • looks/seems

Turkish has no articles like a or the. A bare noun like matkap can mean a drill or the drill, depending on context.

So in a real situation, matkap could be understood as:

• the drill if both speakers know which drill
• a drill if it is being mentioned more generally

Sanki adds the idea of as if, it seems as though, or apparently.

It shows that the speaker is making an impression-based judgment, not stating a certain fact. In this sentence, the speaker is saying the drill gives the impression of being jammed.

Yes, they overlap, and that is normal.

A very common Turkish pattern is:

• sanki ... gibi

This whole combination means as if / as though.

In many sentences, sanki is optional, but gibi is the core element linking the description to the appearance. Using both makes the sentence sound more explicitly tentative or impression-based.

Yes. You can say:

• Matkap sıkışmış gibi görünüyor.

This is completely natural.

Compared with that version, sanki adds a little extra as if / seemingly flavor, but the overall meaning stays very close.

Gibi is a postposition.

That is important for English speakers, because English uses prepositions, but Turkish often uses postpositions. So English says:

• like a machine
• as if stuck

But Turkish puts gibi after the word or phrase:

• makine gibi = like a machine
• sıkışmış gibi = as if stuck

Sıkışmış comes from the verb sıkışmak, which can mean to get stuck, to jam, to be trapped, depending on context.

Here, sıkışmış is a participle/adjectival form built with -mış. It describes a resulting state:

• sıkışmış = stuck, jammed, having got stuck

So in this sentence, it behaves more like a description than a full main verb.

It is related, but here it is not functioning as the main tense of the sentence.

In sıkışmış gibi, -mış is part of a participle-like form describing a state: stuck / having got stuck.

The main finite verb of the sentence is actually:

• görünüyor = looks/seems

So the sentence’s core predicate is not sıkışmış by itself. It is the whole idea sıkışmış gibi görünüyor.

Because sıkışmış focuses on the resulting condition.

• sıkışmış = it appears to be in a stuck/jammed state
• sıkışıyor = it seems to be getting stuck / becoming jammed

In this sentence, the speaker is probably observing the drill and concluding that it already seems jammed, so sıkışmış is more natural.

Here görünüyor means:

• it looks
• it seems
• it appears

It comes from görünmek, which often means to appear / to look / to be visible.

So sıkışmış gibi görünüyor is literally something like:

• it appears as if it is stuck

In modern Turkish, -yor is very commonly used for what English would express as a present-time observation.

So:

• görünüyor = it looks/seems right now

That is the natural choice when you are commenting on what you currently observe.

Görünür is more general, habitual, or formal, and would sound less natural in this kind of immediate everyday observation.

Because Turkish normally places the main finite verb near or at the end.

So the structure is:

• Matkap = subject
• sanki sıkışmış gibi = descriptive phrase
• görünüyor = main verb at the end

This is very normal Turkish word order.

Yes, very much.

The pattern:

• [participle/adjective] + gibi görünmek

is very useful for saying looks/seems as if...

For example:

• yorulmuş gibi görünüyor = he/she looks tired
• kırılmış gibi görünüyor = it looks broken
• hazır gibi görünüyor = it seems ready

So sıkışmış gibi görünüyor fits a very productive Turkish pattern.

There are two different negations, and they mean different things:

• Matkap sanki sıkışmamış gibi görünüyor.
  = The drill looks as if it is not jammed.

• Matkap sanki sıkışmış gibi görünmüyor.
  = The drill doesn’t look jammed.

So you can negate either:

1. the inside description (sıkışmamış)
   or
2. the main verb of appearance (görünmüyor)

That distinction is very useful in Turkish.
