Náhlá

Náhlá is the feminine singular nominative form of the Czech adjective náhlý, meaning sudden or abrupt. It is used to describe feminine nouns in contexts where a quality or event appears quickly and without warning.

In usage, náhlá describes events, changes, or conditions that arise unexpectedly. Common phrases include náhlá změna (a sudden change) and náhlá bolest (a sudden pain). Unlike the adverb náhle, which modifies verbs, náhlá modifies nouns and must agree with the gender and number of the noun it describes.

Etymology and related forms: náhlý is an adjective rooted in the same stem as náhle, the adverb meaning suddenly. The feminine form náhlá shares the same stem and follows the regular patterns of Czech adjectives in -ý/-á/-é, with the stem náhl- remaining constant while the ending marks gender and number.

Grammatical notes: náhlá declines like other adjectives of its class and typically appears directly before the noun it modifies, as in náhlá změna. It can also occur predicatively with linking verbs, for example, Změna byla náhlá (The change was sudden). In standard usage, it conveys a sense of immediacy or rapid onset without implying any particular cause.
