istisnai

Istisnai is a Turkish adjective meaning exceptional or unusual, used to describe things that do not follow the normal pattern or require special consideration. It is common in formal, legal, administrative, or policy texts, as well as in academic writing, where precision about deviations from standard practice is needed.

Etymology and scope: Istisnai derives from the noun istisna, meaning exception or exemption, with the adjectival suffix -i to form a descriptor. The term conveys that a subject, condition, or decision is outside the ordinary rules or norms, often due to specific circumstances or regulatory provisions.

Typical usage: The word frequently occurs with nouns such as durum (situation), koşul (condition), olay (event), karar (decision). Phrases like "istisnai durum" or "istisnai koşul" denote exceptional circumstances; "istisnai karar" refers to an exceptional or unusual decision. In many contexts, istisnai signals a formal or technical nuance rather than everyday rarity.

Nuance and alternatives: Istisnai sits between neutral formal language and stronger terms such as olağanüstü (extraordinary) or sıradışı (unusual). It emphasizes deviation that is recognized or codified, rather than merely surprising.
