Koronák

Koronák is a Czech noun in the plural form. It is the plural of koróna, meaning crown. The stem koróna comes from Latin corona and is used in several domains to denote crown-like shapes or symbols of authority.

Usage of koronák is relatively specialized. In heraldry, regalia, or historical descriptions, koronák can appear when referring to multiple crowns or crown-like objects. In everyday Czech, however, the common plural for the monetary unit koruna is koruny, and for a dental crown the usual term is korunka, so koronák is less frequent and mainly found in formal, scholarly, or inventory contexts.

In astronomy, the standard term for the Sun’s outer atmosphere is koróna; koronák is not typical in contemporary astronomical texts. The concept of corona also appears in other stars, but Czech usage generally avoids koronák in that field.

Etymology and related terms: koronák derives from koróna, which in turn comes from Latin corona. Related Czech forms include koruna (crown or monetary unit) and koróna (astronomical corona); the adjective koronární is used in compounds such as koronární arterie (coronary artery).
