Learn Turkish: Katlanır cihazlar her zaman karmaşık bir mekanizmaya sahiptir. - Folding devices always have a complex mechanism.

It is formed by taking the verb katlanmak (to fold / be folded) and adding the aorist suffix -ır. This creates an aorist participle, which acts like an adjective describing what a noun habitually does or can do. Here, it describes cihazlar as devices that fold (folding devices).

Why is the dative suffix -ya attached to mekanizma?

To express "having" something, Turkish often uses the word sahip (owner) combined with the dative case. Literally, this sentence says the devices are "owners to a complex mechanism" (mekanizmaya sahiptir).

Why does bir come after the adjective karmaşık instead of before it?

In Turkish, the indefinite article bir (a/an) usually sits directly in front of the noun it modifies, after any descriptive adjectives. So, "a complex mechanism" translates to karmaşık bir mekanizma rather than bir karmaşık mekanizma.

What is the purpose of the -tir suffix at the end of sahiptir?

The -tir suffix is a factual "to be" ending (the generalized copula) used to state general facts or universal truths. It gives the sentence an objective tone, which is perfect for describing a general characteristic of all folding devices.
