Opsiyoneldir

Opsiyoneldir is a Turkish grammatical form meaning “is optional.” It is a declarative predicate formed by the adjective opsiyonel (optional) and the third-person singular present copula dir, used to state that a feature or field is not required.

Usage in Turkish is common in formal contexts such as instruction manuals, policy documents, and forms where options are described. It appears in sentences like Bu alan opsiyoneldir (This field is optional) or Bu seçenek opsiyoneldir. The construction expresses a present-tense assertion about the status of a feature, typically in a nominal sentence.

Etymology and terminology: opsiyonel comes from the English word optional, adapted into Turkish. The noun opsiyon means option, and the suffix -el turns it into an adjective meaning “option-related.” The copula -dir is the present tense, third-person singular ending used in formal Turkish. The form may be negated with opsiyonel değildir (is not optional) or replaced in everyday speech with opsiyonel değil, but the former remains standard in official language.

Grammatical notes: The copula has variants -dır, -dir, -dur, -dür depending on vowel harmony with the stem; in opsiyonel, the last vowel is e, so the form is opsiyoneldir. While opsiyoneldir is typical in declarative statements, Turkish also conveys the same idea with simpler constructions in informal speech, such as “bu alan opsiyonel.” The word is primarily used to label or describe optional elements within documents, forms, and guidelines.
