nedlitelné

Nedlitelný is an adjective in Czech meaning not divisible. It is used to describe something that cannot be divided into smaller parts by conventional means and is applied across various fields to indicate indivisibility or unity.

In mathematics, the term is used for integers that have no positive divisors other than 1 and themselves. A natural number greater than 1 with this property is, in standard Czech terminology, a prime number (prvočíslo). The expression nedlitelný is thus a descriptive synonym found in some texts or educational contexts; in everyday mathematical language the term primes is more common. As an example, 2, 3, 5, and 7 are nedlitelná čísla, whereas 4 or 6 are not.

In philosophy, logic and everyday language, nedlitelný can refer to an indivisible whole or unit—something that cannot be meaningfully split without changing its essential nature. This sense connects with historical ideas of indivisibility, such as atomistic notions that a body or substance is composed of indivisible parts.

Etymology and morphology: the word is formed from the prefix ne- (not) and the verb dělit (to divide), plus the adjectival suffix -ný, yielding nedlitelný, literally “not divisible.”
