sistemlerinin

Sistemlerinin is a Turkish noun phrase formed from the word sistem (system) with bound suffixes that express plurality and possession. The base word sistem becomes sistemler (systems) with the plural suffix -ler. The following possessive/genitive suffixes attach to the plural form to indicate ownership by a third party; the combination produces sistemlerinin, commonly glossed as “of their systems” or “their systems’.” Turkish stacks affixes with vowel harmony, so the exact shape of the suffix reflects the surrounding vowels.

In use, sistemlerinin appears in contexts that describe possession or relation between a subject and its systems. It often occurs within larger noun phrases such as phrases of possession or description. For example, in a sentence like Bu şirketin sistemlerinin güvenliği önemliydi, the phrase sistemlerinin güvenliği means “the security of their systems.” Another example is Değişiklikler, sistemlerinin performansını etkiledi, meaning “The changes affected the performance of their systems.” The form can also appear in more complex clauses where the possessor remains clear from context, or where additional modifiers specify which systems are being referred to.

Grammatically, sistemlerinin illustrates how Turkish uses suffix chaining to express number and possession without separate pronouns. It is not a standalone lexical item but a morphological construction that combines root meaning (system) with plural and possessive markers. The same pattern can be observed with other nouns to convey similar relationships, with the suffixes adapting to vowel harmony and syntactic position within a sentence.
