késési

Késési is a Hungarian adjectival form derived from the noun késés ("delay, lateness") and the verb késik ("to be late"). It is used to form adjectives and compound expressions that describe something related to or caused by a delay. The suffix -i in Hungarian creates relational or attributive adjectives (for example, késési díj, "late fee").

In usage, késési commonly appears in technical, legal and administrative contexts as well as everyday language when specifying types or consequences of lateness. Typical collocations include késési idő ("delay time"), késési díj ("late fee"), késési arány ("rate of delay") and késési kártérítés ("compensation for delay"). The form itself is not usually used alone; it functions primarily to modify a following noun.

Pronunciation follows Hungarian phonology: [ˈkeːʃeːʃi]. Grammar follows regular adjective rules: it agrees in position with the noun it modifies and can take attributive or predicative roles when used as an adjective within a sentence. In formal documents and transport timetables, késési is frequent when quantifying or regulating delays; in everyday speech speakers may prefer simpler constructions (e.g., késik, késés van) depending on register.

Related forms include the base noun késés and verb késik, as well as other derivations expressing causation or frequency of lateness.
