Categorize the words into 'countable nouns' and 'uncountable nouns'.

Categorization of Nouns:

• Countable Nouns (исчисляемые существительные): apricot, omelette, bacon, grapefruit, rice, plum, hamburger, lemon, salad, sandwich, tomato, nut, roast beef, cherry, yoghurt, spaghetti, nut
• Uncountable Nouns (неисчисляемые существительные): ham, soup, avocado, coffee, orange, sweet

Explanation:

• Countable nouns are items that can be counted individually and typically have both singular and plural forms (e.g., 'an apricot', 'two apricots').
• Uncountable nouns refer to substances, concepts, or things that are not usually counted as separate units and often do not have a plural form (e.g., 'some ham', 'a lot of soup'). In this exercise, items like 'ham', 'soup', 'avocado', 'coffee', 'orange', and 'sweet' are generally treated as uncountable in common usage, while the others are typically countable.
