Okulum

Okulum is the Turkish word meaning "my school." It is formed by the noun okul (school) plus the first-person singular possessive suffix -um. Turkish is an agglutinative language with vowel harmony, so the exact form of the possessive suffix changes to -im, -ım, -um, or -üm depending on the stem’s vowels. For okul, the last vowel is u, so the suffix is -um, yielding okulum. The phrase can function as a nominal phrase in subject or predicate position; possession can also be expressed with the full pronoun benim as in benim okulum, though okulum is commonly used without the pronoun.

Usage and examples can illustrate how the form works in sentences. Okulum çok güzel means “My school is very beautiful.” Okulumun bahçesi büyük means “My school’s yard is large.” Okulumda yeni bir kütüphane açıldı means “A new library was opened at my school.” Okulumu temizledim means “I cleaned my school,” showing the object form with the possessive. The construction demonstrates Turkish possessive morphology and how affixes attach to the noun to indicate ownership, with the possessor often omitted when the context is clear.
