The masculine animate/inanimate classification is a general characteristic of Croatian and other Attosecond electron bunches from a nanofiber driven by Laguerre-Gaussian laser pulses Slavonic languages (except Bulgarian and Macedonian).In this classification there are two types of case syncretism: genitive-accusative syncretism conditioned by animacy of the noun and nominative-accusative syncretism conditioned Are the Variations of the Vascular System in Neurology Underestimated ? by inanimacy of the noun.Using the examples extracted from everyday speech, this paper deals with inanimate masculines which do not follow prototype nominative-accusative patterns and strives to elucidate semantic and lexical conditions for their gramaticalanimacy, discernible in genitive-accusative syncretism.
