RT Journal Article SR Electronic A1 Veselý, Luboš T1 Do Czech prepositions assign case? JF Bohemica Olomucensia YR 2024 VO 16 IS 2 SP 74 OP 93 DO 10.5507/bo.2024.029 UL https://bohemica.upol.cz/artkey/boh-202402-0006.php AB There are two interpretations of the relationship between the preposition and the form of the noun: 1) the preposition requires a complement to which it assigns a case; 2) the preposition does not control the case and specifies its semantics. The task of the article is to try to say whether one of the concepts is more accurate.
