In the present study the acquisition of negation in early child Polish is investigated and, further, the process is compared with the development of finiteness as a phenomenon being the prior evidence for the implementation of a functional category in children’s grammar. The analysis of Polish child data supports the hypothesis explaining the first language acquisition in terms of a gradual development of the language structure in a child’s mind.enEarly Child PolishPolish L1 acquisitionL1 acquisition of negationPolish as first languageArtykuł
