infantní

Infantní is a Czech adjective meaning relating to an infant or infancy. It is used primarily in scientific, medical, and academic texts to describe phenomena or conditions associated with early life, especially with babies during infancy. The term derives from Latin infans, meaning child or infant, with the Czech suffix -ní forming adjectives.

In medical and biological contexts, infantní is used to denote features or processes characteristic of the infant period. This period in pediatrics is commonly defined as the first year of life, though some definitions extend to the second year. Distinctions are made between infantní, neonatal (newborn, typically the first 28 days), and toddler or early childhood terms.

The word is less common in everyday speech; speakers more often use descriptive phrases like v raném věku or kontextově vysvětlit, že se jedná o kojence, to convey infant-related meaning. When translating or writing for a cross-linguistic audience, infantní can approximate English “infantile” or “infant-related,” though nuances differ.

Related terms include neonatal (neonatální), infant development (infantní vývoj), and infantile disorders (infantní poruchy). The term is mainly encountered in dermatology, neurology, pediatrics, and psychology to describe early-life variants or developmental patterns.
