"Soup without bread"
Translation:Суп без хліба
Because genitive of "хліб" is "хліба." Some masculine nouns in genitive end in а/я and some in у/ю.
There is no a general strict rule, but as the page I referenced in my previous post says: "Whilst most masculine nouns in the genitive end in а or я, there are certain categories of nouns (e.g. abstract concepts, weights and measures, mass nous, locations and institutions, emotions and states of mind, natural phenomena etc.) which mostly have an ending in у or ю, e.g. університет – університету, дощ – дощу, ідеал – ідеалу etc.
In some nouns a change in genitive ending also denotes a change of meaning, e.g. рака – (of a) lobster, раку – (of) cancer, соняшника – (of) sunflower, соняшнику – (of) sunflower seed. You need to be aware of this point, but it is not covered in detail in this course."
